x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker

GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250

Update GNU_PROPERTY_X86_ISA_1_XXX macros:

https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13

in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:

 #define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
 #define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
 #define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
 #define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
 #define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)

The previous GNU_PROPERTY_X86_ISA_1_XXX  macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.

In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.

Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.

Also add

 #define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)

for mask registers.
