runtime(cangjie): Update syntax script

This commit updates `syntax/cangjie.vim` to match the latest `std.core`
library:

New Features:
* Documentation: Added highlighting for documentation keywords (e.g., `@param`, `@return`).
* Standard Library: Added highlighting for `std.core` functions, interfaces, and classes.
* Exceptions: Added highlighting for standard exception types.
* FFI Support: Added highlighting for C interoperability types (e.g., `CPointer`).

Improvements:
* Configuration: Added a unified switch (`s:enabled('builtin')`) for standard library highlighting.
* Type System: Updated `Int` and `UInt` aliases.
* Interpolation: Enabled standard library highlighting inside string interpolation.
* Cleanup: Removed non-core types like `ArrayList` and `HashMap`.

closes: #19085
