Enable Unicode support for RegEx class

Account for file deletion and renaming in Export Presets

Build PCRE2 thirdparty library with unicode support. RegEx objects
in Godot can now be used to recognize unicode strings.

Fix custom property editor layout

starting up or opening the Project Export dialog. Fixes the
error where Godot would attempt to export deleted files that
were previously selected.

Fix potential crash when listing leaked objects

Note:
Casting to the C++ classes and calling the methods there would work as well,
but would require including he header files for the specific object types handled
here, which wouldn't be OK either.

Improve the 3D light documentations
