[ARM][TableGen][MC] Change the ARM mnemonic operands to be optional for ASM parsing (#83436)
This changs the way the assembly matcher works for Aarch32 parsing.
Previously there was a pile of hacks which dictated whether the CC,
CCOut, and VCC operands should be present which de-facto chose if the
wide/narrow (or thumb1/thumb2/arm) instruction version were chosen.
This meant much of the TableGen machinery present for the assembly
matching was effectively being bypassed and worked around.
This patch makes the CC and CCOut operands optional which allows the ASM
matcher operate as it was designed and means we can avoid doing some of
the hacks done previously. This also adds the option for the target to
allow the prioritizing the smaller instruction encodings as is required
for Aarch32.

[Thumb2] support `movs pc, lr` alias for `subs pc, lr, #0`/`eret`
This is used by the Linux kernel built with CONFIG_THUMB2_KERNEL.
Because different operands are not permitted to `movs`, the diagnostics now provide multiple suggestions along the lines of using a non-pc destination operand or lr source operand.

[ARM, Asm] Add diagnostics for general-purpose register operands
This adds diagnostic strings for the ARM general-purpose register
classes, which will be used when these classes are expected by the
assembler, but the provided operand is not valid.
One of these, rGPR, requires C++ code to select the correct error
message, as that class contains different registers in pre-v8 and v8
targets. The rest can all have their diagnostic strings stored in the
tablegen description of them.

[ARM, Asm] Change grammar of immediate operand diagnostics
Currently, our diagnostics for assembly operands are not consistent.
Some start with (for example) "immediate operand must be ...",
and some with "operand must be an immediate ...". I think the latter
form is preferable for a few reasons:
* It's unambiguous that it is referring to the expected type of operand, not
the type the user provided. For example, the user could provide an register
operand, and get a message taking about an operand is if it is already an
immediate, just not in the accepted range.
* It allows us to have a consistent style once we add diagnostics for operands
that could take two forms, for example a label or pc-relative memory operand.

[ARM] Use table-gen'd assembly operand diags in ARM asm parser
This switches the ARM AsmParser to use assembly operand diagnostics from
tablegen, rather than a switch statement on the ARMMatchResultTy. It
moves the existing diagnostic strings to tablegen, but adds no new ones,
so this is NFC except for one diagnostic string that had an off-by-1 error
in the hand-written switch statement.

[ARM] Use new assembler diags for ARM
This converts the ARM AsmParser to use the new assembly matcher error
reporting mechanism, which allows errors to be reported for multiple
instruction encodings when it is ambiguous which one the user intended
to use.
By itself this doesn't improve many error messages, because we don't have
diagnostic text for most operand types, but as we add that then this will allow
more of those diagnostic strings to be used when they are relevant.
