    RISC-V: Add support for the Zvkng ISA extension
    
    Zvkng is part of the vector crypto extensions.
    
    Zvkng is shorthand for the following set of extensions:
    - Zvkn
    - Zvkg
    
    bfd/ChangeLog:
    
            * elfxx-riscv.c: Define Zvkng extension.
    
    gas/ChangeLog:
    
            * testsuite/gas/riscv/zvkng.d: New test.
            * testsuite/gas/riscv/zvkng.s: New test.
