  [BOLT][AArch64] Add support for short LLD thunks/veneers (#118422)

When a callee function is closer than 256MB from its call site, LLD
linker can strategically create a short thunk for the function with a
single branch instruction (that covers +/-128MB). Detect and convert
such thunks into direct calls in BOLT.
