Unlike \S, \w only matches characters which are valid in identifiers. This
seems to be much faster, especially for longer identifier names.

We haven't measured any noteworthy perf improvement
from these, and they are difficult to port to NIR,
so remove them before the NIR based VS input lowering
in order to make it easier to bisect and analyze stats.

The meson.build_root() method has been deprecated, so let's switch to
meson.project_build_root(), which usually means the same thing. The case
where it doesn't do the same thing is if Mesa is a subproject to some
other project, but in that case I believe we want the build root of Mesa,
not of the parent project anyway.
