This pr introduces some cargo features. For `swc_common` and `swc_ecma_ast`, it introduces a feature flag `fold`.
`Fold` and `Visit` traits exist only if the feature is enabled.
For `swc_ecma_parser`, flag called `verify` is added. When disabled, we skip checking of validity of some expressions.
e.g. `{foo = bar}`
Verification is disabled by default it requires nightly compiler
swc_atoms:
- add some atoms
swc_ecma_ast:
- ast nodes for typescript
- `ClassMethod` -> `Method`, `ClassMethodKind` -> `MethodKind`
- private class method / class property
- use separate type for tagged template literals

- make function body optional
swc_ecma_parser:
- rename Type to TokenContext
- support decorators
Note: error reporting for invalid decorator is not implemented yet
- merge `Config` into `Syntax`
- Use DiagnosticBuilder for error type
This is to make backtracking cheaper.

It now shows the code failed to parse

swc:
- add nodejs binding
`Map<T>` adds a method named `map` which is actually `Box<T>` -> `Box<T>` without reallocation.

This macro deeply joins path at 'Type' level.

ecma_transforms:
- implement es2015::instanceof
- implement es2015::typeof_symbol
- implement inline_globals pass
ecma_parser:

- `swc_macros` is removed. Now macros are imported with `extern crate macro_name` instead of `extern crate swc_macros`.
- manage atoms with words.txt file
- do not reexport swc crates

- fix str.length
- ignore some tests
compat:
- fix `**=`
- fix es3::prop_lits
common:

using Visitor.
* Remove some other unused stuffs.
* Change public path of swc_common::fold::* to swc_common::*.
- Parser and lexer for lastest ecma spec https://tc39.github.io/ecma262
- Lexer is currently very inefficient
- Use https://github.com/tc39/test262-parser-tests/ for testing.
- Implement proc-macro based ast folder and assert_eq_ignore_span! based on it.
- Some utilities for proc macro at /macros/common
