[mho22]

Motivation for the change, related issues

This pull request refactors code in PHP compilation / shared libraries and PHP.wasm Node / PHP.wasm web to keep consistency. This follows up on the split PHP.wasm packages into per PHP version packages pull request.

Implementation details

• Removed obsolete icudt74l.js and icudt74.dat files
• Moved public/shared directory inside extensions/intl in consistency with the node structure [ Bug ]

• Removed unused vite-external-dynamic-imports Vite plugin. Not needed anymore.
• Moved Node xdebug directory inside extensions directory alongside intl
• Simplified shared libraries build commands in consistency with PHP build
• Simplified PHP build commands
• Cloned PHP repository based on the tag name instead of the branch name [ e.g. branch 8.2.30 doesn't exist while tag 8.2.30 does ] [ Bug ]
• Added currentDirPath in php.js files similarly to the node-builds/*/src/index.ts files.
• Rebuilt shared libraries

Alright, alright, alright! This is now ready for review!

@bgrgicak As this pull request fixes a bug in PHP.wasm Web and PHP.wasm Compile, I think we could maybe review this pull request this week? But I get a hard time listing the file changes since there are a lot [ Especially .so, .wasm, ... files ].

This pull request is mostly deleting obsolete files, rewriting code to keep consistency and fixing bugs.
