  [LLD][AArch64] Add test for missing AArch64 BTI thunk (#116665)

A follow up to PR #116402 to add a regression test. The original change
fixed the reproducer but that was not suitable to use as a regression
test.

This test case will fail with a LLD prior to #116402.

The disassembly for the thunk that starts as a short thunk but is later
a long thunk isn't quite right. It is missing a $d mapping symbol. I
think this can be fixed, but I've not done that in this patch to keep it
test only. It is not a regression introduced in #116402.

I've also removed a spurious --threads=1 I noticed in the original test
aarch64-thunk-bti.s
