Joel Sing 0a17b2c174 cmd/internal/obj/arm64: load large constants into vector registers from rodata
Load large constants into vector registers from rodata, instead of placing them
in the literal pool. This treats VMOVQ/VMOVD/VMOVS the same as FMOVD/FMOVS and
makes use of the existing mechanism for storing values in rodata. Two additional
instructions are required for a load, however these instructions are used
infrequently and already have a high latency.

Updates #59615
