migration/xbzrle: Use i386 host/cpuinfo.h
...
Perform the function selection once, and only if CONFIG_AVX512_OPT
is enabled. Centralize the selection to xbzrle.c, instead of
spreading the init across 3 files.
Remove xbzrle-bench.c. The benefit of being able to benchmark
the different implementations is less important than not peeking
into the internals of the implementation.

util: import GTree as QTree
...
The only reason to add this implementation is to control the memory allocator
used. Some users (e.g. TCG) cannot work reliably in multi-threaded
environments (e.g. forking in user-mode) with GTree's allocator, GSlice.
See https://gitlab.com/qemu-project/qemu/-/issues/285 for details.
Importing GTree is a temporary workaround until GTree migrates away
from GSlice.
This implementation is identical to that in glib v2.75.0, except that
we don't import recent additions to the API nor deprecated API calls,
none of which are used in QEMU.
I've imported tests from glib and added a benchmark just to
make sure that performance is similar. Note: it cannot be identical
because (1) we are not using GSlice, (2) we use different compilation flags
(e.g. -fPIC) and (3) we're linking statically.
