Change march=alderlake ISA list and add m_ALDERLAKE to m_CORE_AVX2

Alder Lake Intel Hybrid Technology will not support Intel® AVX-512. ISA
features such as Intel® AVX, AVX-VNNI, Intel® AVX2, and UMONITOR/UMWAIT/TPAUSE
are supported.

gcc/ChangeLog

	* config/i386/i386.h (PTA_ALDERLAKE): Change alderlake ISA list.
	* config/i386/i386-options.c (m_CORE_AVX2): Add m_ALDERLAKE.
	* common/config/i386/cpuinfo.h (get_intel_cpu): Add AlderLake model.
	* doc/invoke.texi: Change alderlake ISA list.
