internal/runtime/gc/scan: import scan kernel from gclab [green tea]

This change imports the AVX512 GC scanning kernel from CL 593938 into a
new package, internal/runtime/gc/scan. Credit to Austin Clements for
most of this work. I did some cleanup, added support for more size
classes to the expanders, and added more testing. I also restructured
the code to make it easier and clearer to add new scan kernels for new
architectures.

For #73581.
