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

- 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:**
