[rcore] LoadDirectoryFilesEx(), count files if not recursive (#5496)

* LoadDirectoryFilesEx on not recursive loading count files

* Removed FilePathList.capacity

* Added security check in case of memory leak

* Fix stop loading paths early on recursive loading

* Fix count directories only if filter contains DIRECTORY_FILTER_TAG

* rlparser: update raylib_api.* by CI

* GetDirectoryFileCount() and GetDirectoryFileCountEx() made visible

* rlparser: update raylib_api.* by CI

* Added new file and directories filter tags

* Renamed `fileCount` in `ScanDirectoryFiles()` to `expectedFileCount`
