Upon investigating the extremely slow MSVC build times in #80513, I noticed
that while Godot policy is to never use exceptions, we weren't enforcing it
with compiler flags, and thus still included exception handling code and
stack unwinding.
This is wasteful on multiple aspects:
- Binary size: Around 20% binary size reduction with exceptions disabled
for both MSVC and GCC binaries.
- Compile time:
* More than 50% build time reduction with MSVC.
* 10% to 25% build time reduction with GCC + LTO.
- Performance: Possibly, needs to be benchmarked.
Since users may want to re-enable exceptions in their own thirdparty code
or the libraries they compile with Godot, this behavior can be toggled with
the `disable_exceptions` SCons option, which defaults to true.
They haven't been updated for years and still use the old MainLoop
basic framework instead of the new doctest one.
They're of dubious quality and best redone from scratch using the
new framework.
This has been superseded by GDExtension so this code is no longer useful
nor usable.
There's still some GDNative-related stuff in platform export code which
needs to be adapted for GDExtension (e.g. to include GDExtension libraries
in exports).
GDNative-specific tests moved out of main `tests/` folder into
`modules/gdnative/tests`.
Include path for GDNative headers are still hardcoded in `tests/SCsub`,
but made conditional now.
Also fixed test case tag typos.

Allows switching `tests=yes`/`no` and rebuilding only tests and main,
instead of the whole engine.
