GDB conditionally defines HWCAP2_MTE in gdb/arch/aarch64-mte-linux.h, but that's not the best place for it since it's a definition that should be used only in native code so move it to gdb/nat/aarch64-mte-linux-ptrace.h. Introduce an AARCH64_HWCAP2_MTE in gdb/arch/aarch64-mte-linux.h to be used by target-dependant code. Similarly, add AARCH64_ prefix to the SEGV_MTEAERR and SEGV_MTESERR definitions in gdb/arch/aarch64-mte-linux.h. I noticed that enum class aarch64_memtag_type is only used in native code, so move its definition to gdb/nat/aarch64-mte-linux-ptrace.h as well. I also noticed that gdb/aarch64-linux-tdep.h defines AARCH64_LINUX_SIZEOF_MTE_REGSET which is redundant with AARCH64_LINUX_SIZEOF_MTE, already defined in gdb/arch/aarch64-mte-linux.h so consolidate both definitions. Finally, the include of arch/aarch64-mte-linux.h isn't used in gdb/aarch64-linux-nat.c nor in gdb/nat/aarch64-mte-linux-ptrace.c so remove it from them.
