LoongArch: Fix missing plugin header for cpu-features.h [PR125362]

When compiling GCC plugins that include target headers on LoongArch,
the build fails because cpu-features.h is not installed during
`make install-plugin`.  The header, included by loongarch-protos.h,
was not listed in any variable that feeds PLUGIN_HEADERS.  Add it to
TM_H, following the same approach used by i386 for i386-cpuinfo.h.

gcc/ChangeLog:

	PR target/125362
	* config/loongarch/t-loongarch (TM_H): Add
	common/config/loongarch/cpu-features.h.
