This fixes compilation for msvc ABI. This currently only works under Windows,
I believe because Zig requires the Windows SDK to be present for msvc compilation
/ does not allow cross compilation with MSVC. Still, this is nice to have.

Not sure why we had these here, but alignment on a packed struct seems somewhat
nonsensical (after all, it's fields are packed as closely together as possible
so what would alignment refer to?) removing seems fine and fixes compilation with
latest Zig:
```
/Users/slimsag/Desktop/hexops/mach/gpu-dawn/libs/mach-glfw/src/hat.zig:8:20: error: unable to override alignment of packed struct fields
up: bool align(@alignOf(u8)) = false,
^
/Users/slimsag/Desktop/hexops/mach/gpu-dawn/libs/mach-glfw/src/mod.zig:10:23: error: unable to override alignment of packed struct fields
shift: bool align(@alignOf(c_int)) = false,
``` ^

This change both restricts and clarifies the mutability/nullability of the pointers, and replaces the explicitly-typed pointer usage in setUserPointer with ?*anyopaque, since it now, as of being renamed from c_void, more simply communicates the intent of taking any pointer type.
repatch undefined behavior in GLFW which did not land yet and was accidentally removed when updating GLFW in #136
See glfw/glfw#1989Fixeshexops/mach#149
* add wayland-headers include path
* add wayland protocols header to wayland target includes
* move `xkb_unicode.c` to `sources_linux.c`
* glfw: document where wayland generated sources come from
* glfw: update sdk-linux-x86_64 to include Wayland protocol sources

This consistently shaves off about 40ms (~130ms -> ~90ms, 30% reduction) from build times when iterating.
On Windows, I suspect the result will be much greater due to slow filesystem perf there and the fact
that this reduces the # of files read.
This was originally brought to my attention as a possibility by @meshula in hexops/dawn#2, the way this
works is by reducing compilation units so that C headers only need to be read/parsed/interpreted once
rather than once per individual C source file we are compiling.

This substantially reduces consecutive build times when using mach/glfw.
`system_sdk.getSdkPath` is frequently invoked as part of the build process, and previously it was
doing some fairly involved work (ensuring the native SDK is at the right revision, needless
`git fetch` in native SDKs to check for updates, etc.)
We now do far less work in `getSdkPath`, and additionally cache the result in-memory. This improves
build times substantially, but especially so with consecutive (non-cold-cache) build times:
* For `mach/glfw`: ~2s before, ~160ms after
* For `mach/gpu`: , ~16s before, ~3.6s after
