This improves type safety and is less verbose. Use SimpleTy only where
an integer is needed like switches or emitting a VBR.

(#158426)
cPTR is a wildcard CHERI capability value type, used analogously to iPTR. This allows TableGen patterns to abstract over CHERI capability widths.

Without this patch, the constructor arguments come from
SmallVectorImpl, not ArrayRef. This patch switches them to ArrayRef
so that we can construct SmallVector with a single argument.
Note that LLVM Programmer’s Manual prefers ArrayRef to SmallVectorImpl
for flexibility.

(#99537)
The original `CheckValueTypeMatcher` stores StringRef as the member
variable type, however it's more efficient to use use
MVT::SimpleValueType since it prevents string comparison in isEqualImpl,
it also reduce the memory consumption in each object.

Refactor of the llvm-tblgen source into:
- a "Basic" library, which contains the bare minimum utilities to build
`llvm-min-tablegen`
- a "Common" library which contains all of the helpers for TableGen
backends. Such helpers can be shared by more than one backend, and even
unit tested (e.g. CodeExpander is, maybe we can add more over time)
Fixes #80647
