  [ARM] Remove unused class member in ARMConstantIslandPass (#141093)

The map variable `BlockJumpTableRefCount` was added in commit
f5f28d5b0ce76af8f6944774aa73bad9e328b020 to track whether a basic block
was the target of any jump table entries. This was used in the function
`fixupBTI` to insert and remove BTIs after jump tables had been
modified.

Commit 3b742242a53ed0c2a2e1b6bb2352cace43c22030 removed `fixupBTI` on
the grounds that the work was now being done elsewhere. That left
`BlockJumpTableRefCount` still being created, but now nothing is using
it. So we can garbage-collect that variable and all the code that
populates it.
