[ php-wasm ] Remove static intl extension artifacts (#2970)

## Motivation

This pull request removes all remaining code related to the static
`intl` extension, which is no longer used in the project. Cleaning up
these files avoids confusion with the new dynamic `intl` extension.

## Implementation Details

- Removed `WITH_INTL` from `compile/php/build.ts`
- Removed `lib_intl` from `compile/Makefile`
- Removed the `libintl` directory under `compile/`
