_dl_tlsdesc_dynamic should also preserve AMX registers which are
caller-saved. Add X86_XSTATE_TILECFG_ID and X86_XSTATE_TILEDATA_ID
to x86-64 TLSDESC_CALL_STATE_SAVE_MASK. Compute the AMX state size
and save it in xsave_state_full_size which is only used by
_dl_tlsdesc_dynamic_xsave and _dl_tlsdesc_dynamic_xsavec. This fixes
the AMX part of BZ #31372. Tested on AMX processor.
AMX test is enabled only for compilers with the fix for
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114098
GCC 14 and GCC 11/12/13 branches have the bug fix.
