fix(es/codegen): Check for trailing comments while emitting an arrow (#8257) 
**Description:**

This PR also **fixes** the `Default` implementation of `JsMinifyFormatOptions`. It didn't matched the default value when it's used with `serde::Deserialize`.

I did more investigation by monkey-patching the `next` package.
`.minify()` resolved without an exception.
It means that `.minify()` is producing an invalid ES code.

So... candidates are

refactor(es/typescript): Reimplement TypeScript pass (#7202) 
**Description:**

## Bugfixes
- Exported `let`/`var` declarations in TypeScript namespaces should be mutable.
- Fix missing declaration of complex exported patterns in TypeScript namespaces.
- Preserve concrete TS namespaces.

## New Features
- Introducing [Verbatim Module Syntax](https://www.typescriptlang.org/tsconfig#verbatimModuleSyntax).
- Enum value will now be inlined whenever possible within a single module, optimizing runtime performance.
- Constant enums will be automatically eliminated when feasible, This can reduce bundle size.
- Added support for cross-referencing enum values.

## Deprecated
`TsEnumConfig` is deprecated
  - The `treat_const_enum_as_enum` transform option is deprecated.
  - The `ts_enum_is_readonly` assumption option is deprecated.

**BREAKING CHANGE:**

TypeScript Config is changed.

fix(es/codegen): Fix placing of comments of yield arguments (#7858) 
**Description:**

Looks like the bug I ran into had nothing to do with the changes in
#7856, since it's reproducible without it. Looks like it might have only
surfaced now because https://github.com/swc-project/swc/pull/7853
changed the default value of `jsc.minify.format.comments`? Added a
minimal test case here with the expected result.

Here's the actual output:

```js
 export var padding = '';
 export function exec2({ commands }) {
     return __awaiter(this, void 0, void 0, function*() {
         for(let i2 = 0; i2 < commands.length; i2++){
             let command = commands[i2];
             yield // some-comment
             function({ command }) {
                 command();
             }({
                 command,
                 handleError
             });
         }
     });
 }
```

The comment ends up getting added after the yield, which makes the
output invalid.

Going to see if I can figure out a fix tomorrow, but let me know if you
have any ideas on where to start looking in the meantime!

fix(es/codegen): Fix LineCol calculation of printed files (#6763) 
**Description:**

There were several issues with the way we updated the current `LineCol` position during the printing of the generated file:

- We used `chars` and `char_indices` (UTF-32) instead of `encode_utf16` (UTF-16) chars.
- JS uses UCS-2 (basically UTF-16) for its strings, and source maps default to that implicitly.
- `\r` was incorrectly handled
  - it didn't add a `line_start`; only `\n` did
- `\r\n` was incorrectly handled
- It was trying to let the `\n` path handle the `line_start`, but it called
`chars.next()` which ate the `\n` char.

I also took the opportunity to avoid the `Vec` allocations and reduced some code duplication.
