[JITLink][AArch32] Multi-stub support for armv7/thumbv7 (#78371)
We want to emit stubs that match the instruction set state of the
relocation site. This is important for branches that have no built-in
switch for the instruction set state. It's the case for Jump24
relocations. Relocations on instructions that support switching on
the fly will be rewritten in a relaxation step in the future. This
affects Call relocations on `BL`/`BLX` instructions.
In this patch, the StubManager gains a second stub symbol slot for each
target and selects which one to use based on the relocation type. For
testing, we select the appropriate slot with a stub-kind filter, i.e.
`arm` or `thumb`. With that we can implement Armv7 stubs and test
that we can have both kinds of stubs for a single external symbol.
