**Description:**
Now, `TokenContext` is 1 byte, so we can increase the stack size for it.

**Description:**
- `TokenContexts` now uses smallvec, as the element type is very small (1 byte) now.
- Some codes are moved to allow CPU to cache code correctly.
**Description:**
`EsConfig` and `TsConfig` sound like a general configuration for the whole language, while actually it's only about parsing.
To avoid a breaking change, I created type aliases that will work without changing the code, while warning the users.
**Related issue:**
- Closes#9089.
**Description:**
In the fast path, we don't even use the buffer.

**Description:**
TsPropertySignature can not have params, type params, or an initializer.
**BREAKING CHANGE:**
Yes. Any users looking into these fields should stop - they are always empty.

> I found part of the problem:
>
> U+30FB was added to `ID_Continue` from Unicode version 14 to 15, but v8 is using an older version of unicode ... which I can't find the exact version.
>
> I spent 2 hours searching for all the missing pieces, I give up.
>
> Let me back port unicode version 14.
