aarch64: FP8 scale and convert - Implement minor improvements
Following feedback received shortly after the initial commit of the
aarch64 instructions for scaling and converting fp8 instructions, this
patch addresses the issues raised in the relevant feedback.
This includes the following changes:
* Standardize all FP8 qualifier-set names. This has resulted in the
renaming of QL_V2FP8B8H to QL_V2_HB_LOWER and, likewise, QL_V28H16B
to QL_V2_HB_FULL.
* Update `FP8_INSN' aarch64_opcode_table[] entries to reflect the new
standardized qualifier-set names mentioned above and, in the case of
the "fcvtn" entries, also add a leading 0 to their opcode values so
they are given as 8 hexadecimal digits in length to ensure
consistency in formatting relative to other entries in the table.
* Revise the added test-cases so that when checking operand fields in
the disassembled binaries, all bits for these fields get tested to
ensure they can be toggled on/off by the relevant operand arguments.
