SCsub: Add python shebang as a hint for syntax highlighting Also switch existing shebangs to "better" /usr/bin/env python.

SCons: Format buildsystem files with psf/black Configured for a max line length of 120 characters. psf/black is very opinionated and purposely doesn't leave much room for configuration. The output is mostly OK so that should be fine for us, but some things worth noting: - Manually wrapped strings will be reflowed, so by using a line length of 120 for the sake of preserving readability for our long command calls, it also means that some manually wrapped strings are back on the same line and should be manually merged again. - Code generators using string concatenation extensively look awful, since black puts each operand on a single line. We need to refactor these generators to use more pythonic string formatting, for which many options are available (`%`, `format` or f-strings). - CI checks and a pre-commit hook will be added to ensure that future buildsystem changes are well-formatted.

Replacement of internal RegEx with PCRE2 The pattern and replacement matching behaviour has been changed purely due to the nature of switching to a standards-compliant library. One mistake in the previous behaviour was that named groups didn't have a number. This has been corrected. As names are actually just an alias of numbered groups, RegExMatch::get_name_dict() is now get_names() and is a dict referring to the group number it represents. Duplicate names are enabled and the with the first matching instance used. Due the lack of a suitable equivalent in PCRE2, RegExMatch::expand() was removed.

drivers: Refactor SCsub and drop redundant env_drivers clone The reordering of the SConscript includes allows to ensure that stuff like the builtin zlib headers will be available for libpng. Also moved glew back into global env, otherwise windows seems not to find it... Kind of shooting in the dark with this multi-env setup.

SCons: Add explicit dependencies on thirdparty code in cloned env Since we clone the environments to build thirdparty code, we don't get an explicit dependency on the build objects produced by that environment. So when we update thirdparty code, Godot code using it is not necessarily rebuilt (I think it is for changed headers, but not for changed .c/.cpp files), which can lead to an invalid compilation output (linking old Godot .o files with a newer, potentially ABI breaking version of thirdparty code). This was only seen as really problematic with bullet updates (leading to crashes when rebuilding Godot after a bullet update without cleaning .o files), but it's safer to fix it everywhere, even if it's a LOT of hacky boilerplate.
