jade 0f99ed43f1 build-time: remove 20% more by PCH'ing C++ stdlib
It seems like someone implemented precompiled headers a long time ago
and then it never got ported to meson or maybe didn't work at all.

This is, however, blessedly easy to simply implement. I went looking for
`#define` that could affect the result of precompiling the headers, and
as far as I can tell we aren't doing any of that, so this should truly
just be free build time savings.

Previous state:
Compilation (551 times):
  Parsing (frontend):         1302.1 s
  Codegen & opts (backend):    956.3 s

New state:
**** Time summary:
Compilation (567 times):
  Parsing (frontend):         1123.0 s
  Codegen & opts (backend):   1078.1 s

I wonder if the "regression" in codegen time is just doing the PCH
operation a few times, because meson does it per-target.

# NOTE(Qyriad): This file is one big slab of boilerplate.
# Lix's current unit test organization is scattered and entagled.
# Each of the test-support libraries could theoretically be a somewhat self-contained
# subdir(), but literally nothing else can. Each of the tests have dependencies on other
# test support libraries, and so do their support libraries.
# Each of the tests have dependencies on their own andother test support libraries,
# and so do their support libraries, and they have entangled dependencies on Lix's mainline
# lib* targets as well.
# The only boilerplate reduction I really could do here is throw everything in big nested dictionaries
# and dynamically generate and refer to targets based on abstracted specs, but without user-defined
# functions, the result would be way less readable than just a bit of copypasta.
# It's only ~200 lines; better to just refactor the tests themselves which we'll want to do anyway.
