refactor(es/parser): Do not use lexical (#7758) 
This PR replaces the current usage of lexical within the swc_ecma_parser
crate with equivalent parsing of large numbers using BigInt.

**Description:**

As discussed in
https://github.com/swc-project/swc/issues/7752, lexical contains a
number of soundness issues but doesn't appear to be actively supported.
Given the relatively low integration surface it seems reasonable to
replace the usage of lexical with another package to avoid this issue.

**Related issue:**

- Closes #7752

fix(plugin/runner): Disable wasi env cleanup (#7607) 
**Description:**

Even after setting shared runtime for the wasi env, `cleanup` still panics. I suspect something internal to cleanup doesn't honor those handles correctly; for now, disable it and try to see if this works.

As commented, this is not a huge issue as the plugin usually doesn't have resources to be cleaned up anyway.

fix(xml/codegen): Fix wrong minification of spaces in a self-closing tag (#7595) 
**Description:**

xml codegen with option `minify: true`.

input:
```xml
<foo attributeName="OK" />
```

expected:
```xml
<foo attributeName="OK"/>
```

actual:

```xml
<foo attributeName="OK" />
```

---

We already escape the attribute value in `escape_string` function, so we
do not need to check whether it contains a specific string.

It also optimizes the AST for runtime evaluation. Before, we constructed
a leftwards conditional tree (`(_a_b = (_a = a) == null ? void 0 : _a.b)
== null ? void 0 : _a_b.c`) instead of a rightward tree (`(_a = a) ==
null ? void 0 : (_a_b = _a.b) == null ? void 0 : _a_b.c`), which
required multiple `== null` checks after the first nullish is found.

refactor(plugin/runner): Revise cache, module loading (#7408) 
**Description:**

One of the oversight around design of `TransformExecutor` is
encapsulating plugin module logic. It has access to the cache and do its
own loading & storing. This means consumer of plugin runner have tricky
challenge to control its caching system. First, there is no way to
escape how swc_plugin_runner controls cache and cannot synchronize into
their own, also depends on the usecases cannot control the features they
want to opt in: for example, there's no way one interface uses in-memory
cache, and another uses filesystem since it is compile time configured
singleton.

PR revisits overall design of TransformExecutor: now it accepts a tratir
`PluginModuleBytes`, which abstracts any kind of bytes we are dealing
with, such as raw file slice or serialized `wasmer::Module`. Cache
instantiation and managing is now bubbled up to the application level
(`swc` in here), so if someone wants non-singleton caching or integrate
into their own caching system it can be customized.

Lastly, deprecated `memory_cache` feature and only exposes
`filesystem_cache`. Cache implementation uses in-memory is always
available, and can opt in filesystem cache where it's supported.


**BREAKING CHANGE:**

This is clearly breaking changes for the consumers of swc_core. for the
@swc/core, this PR takes care of necessary changes. I'll work on
next-swc changes later once we have new @swc/core version with this
changes.

fix(es/minifier): Mark all function params as potential property mutation (#7409) 
**Description:**

This issue is more severe than I originally thought. It raises not in
array indexing, but in function calls and property mutation. We should
treat all function arguments as potentially be property mutated,
otherwise following example

```js
class A {
	a = 1

	toString() {
		return this.a
	}
}

const a = new A()

function foo(x) {
	x.a++
}

const b = a + 1

foo(a)

console.log(b)
```

would be error(It should log 2, but logs 3 after compress).

As the result, massive regressions is unavoidable, since some of these
optimizations may indeed cause error. Part of them can be mitigated with
following optimization -- allow inline of ident even if its original
value is mutated. Consider

```js
export function foo(x) {
   const y = x
   x.a = 1
   y.b = 2
}
```

If x is a primitive value, all mutations to its properties are ignored;
if x is a object, then y refers to the same object no matter what
mutation is performed.

And there's still room for more, currently following code
```js
export function foo(x) {
    const y = Math.floor(x);
    g(y);
}
```
But I'd rather do it in a separate PR.

feat(swc_core): Allow native env plugin to use memory cache (#7390) 
**Description:**

I just realized there could be some case who'll want plugin in native env, but without filesystem cache. If there's a custom cache implementation, it'll make a conflict to swc's caching mechanism since swc does not expose any interface to the its cache.

PR takes simple approach to expose another feature to opt in native env with memory cache for those case. Ideally we should make `plugin_transform_host_native` to not to opt-in any cache, and then make `swc_plugin_runner` to run without any cache implementation - but that'll be a breaking changes with few more involved changes.

feat(plugin): Enable bytecheck (#7280) 
**Description:**

Second attempt to enable bytecheck. This PR does not have versioned struct yet, just enabling bytecheck wherever possible. Also, it is for the ast only yet, so transform metadata and others might need this later.

PR seems to be passing all the ci, but as we've experienced before, there might be some unexpected outcomes with the release. Maybe better to hold this until clear https://github.com/swc-project/swc/issues/7238, then land as a separate release.

feat(plugin/runner): Improve caching (#7341) 
**Description:**

Previously disabled cache (storing compiled module in memory) still doesn't work, so falling back to storing raw bytes and create new module each time. This is the same behavior to the wasm build's approach.

Also minor improved caching root to include more information. Previous rustc didn't seem to work unfortunately, so removed but instead using plugin_runner's version.

fix(common): Workaround the Arc and rkyv issue (#7321) 
**Description:**

Attempt to workaround #7238.

Originally I thought this is related with oom or memory layout, then realized actual deserialization error occurs in weird position - it tries to deserialize BytePos (which is obvious type) and it fails. It made me think maybe a property next to the struct layout have some unexpected behavior, notably Arc<String>.

PR applies same workaround as Atom does, and it seems to at least pass swc-coverage-instrument's usecases. May need bit more verification with other plugins to see if we can call this out as reliable workaround.
