CI: Build with Mono 6.12.0.144 + other env updates

Update env components to these versions:

- Python 3.9
- Pin NDK to 21.4.7075529 as done by Godot

Not updating Android API level to 30 yet as some feature work is needed in
Godot to support new requirements.

Mono 6.12.0.144 is still a Preview release, but contrarily to 6.12.0.122,
it has a successful Windows build. It also theoretically finalizes support
for Apple M1, so we can attempt using it to build Mono for that arch.

 These scripts are based on the Mono [sdks](https://github.com/mono/mono/tree/master/sdks) makefiles, with some changes to work well with Godot.

+## Compiling Godot for Desktop with this Runtime
+
+In order to compile mono into Godot for deskop you will need to first build for desktop (see 'Desktop' below), and then Base Class Libraries (see 'Base Class library' below).
+
+Then run the 'copy-bcl' action of the same desktop script you ran configure and make on, specifying the same target platforms you used before. This will copy the bcl runtime into the runtime directories that the subsequent Godot build (using `copy_mono_root=yes`) expects to find them in.
+e.g.
+`./linux.py copy-bcl --target=x86 --target=x86_64`
+
+Then you'll need to compile Godot using `copy_mono_root=yes`
+e.g.
+`scons -j6 target=release_debug tools=yes module_mono_enabled=yes copy_mono_root=yes mono_prefix="$HOME/mono-installs/desktop-linux-x86_64-release"`
