[examples] core_directory_files fixes (#5343)

* [examples] reset on folder click

`continue` after clicking a new folder

* [examples] don't make non-directories clickable

`IsPathFile` is not enough to check if it's a directory
since it also takes in char devices.

* rlparser: update raylib_api.* by CI

* Delete tools/rlparser/rlparser
