3ec74222e6 glfw: reduce compilation units to bring iteration time down to ~90ms 
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.

77d2e8a9a3 glfw: improve consecutive build times by 4-12x 
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

cb4f911782 glfw: Fix pointer cast 
The GLFW implementation takes a constant pointer to a `VkAllocationCallbacks` struct; casting it to a mutable pointer equivalent here doesn't break anything, but does prevent passing a valid const pointer, which is often what one should prefer to do.
As well, the `@alignOf` builtin takes the alignment expected of the type directly, so `@alignOf(*T)` returns the alignment of `*T`, not `T`, so that has also been corrected.

979a8bc978 glfw: make system_sdk pin versions, auto-update 
Prior to this change, an older commit of Mach or mach-glfw would use the latest
version of the native system SDKs, which would sometimes be incompatible. Better
is to ensure that we actually pin the revision we're using, so a given revision
of mach or mach-glfw is using a specific revision of the native SDKs.

Similarly, we previously had no mechanism for updating SDKs: it was either cloned,
or it wasn't. This introduces a simple `git fetch` prior to hard-resetting the SDK
to the target pinned revision - effectively giving us automatic updates for anyone
using an older revision.
