    [gdb/testsuite] Require compilation flags in two gdb.arch/aarch64 test-cases
    
    With test-cases gdb.arch/aarch64-mte-core.exp and gdb.arch/aarch64-pauth.exp I
    run into compilation errors due to unsupported compilation flags.
    
    Fix this by requiring the compilation flags, such that I have instead:
    ...
    UNSUPPORTED: gdb.arch/aarch64-mte-core.exp: require failed: \
      have_compile_flag -march=armv8.5-a+memtag
    UNSUPPORTED: gdb.arch/aarch64-pauth.exp: require failed: \
      have_compile_flag -mbranch-protection=pac-ret+leaf
    ...
    
    Tested on aarch64-linux.
