aarch64: Add +d128 architectural feature support
Indicating the presence of the Armv9.4-a features concerning 128-bit
Page Table Descriptors, 128-bit System Registers and Instructions,
the "+d128" architectural extension flag is added to the list of
possible -march options in Binutils, together with the necessary macro
for encoding d128 instructions.
