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.

feat(es/resolver): Use different syntax context for unresolved refs (#4436) 
- We don't need a list of bindings to check if an identifier is unresolved.
 - Checking if an identifier is unresolved is now one CPU instruction.
   - Previously it was one hashmap operation.
 - This PR also improves performance, by removing the hashmaps mentioned above.
