Initial work on Vulkan: -Added VulkanContext -Added an X11 implementation -Added a rendering device abstraction -added a Vulkan rendering device abstraction -Engine does not work, only shows Godot logo (run it from bin/)

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.

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.

Vulkan-Loader: Mark secure_getenv as available on Linux It's a GNU extension part of glibc since 2.17, and it was also added recently to musl libc. It doesn't seem to be available on *BSD (but also not used there by Vulkan-Loader). Could be made more thorough by doing a test compilation of a file to check for the existence of the function on the host system, but unless we run into actual issues, that's likely overkill.
