  [LLVM][ARM][CodeGen]Define branch instruction alignment for m85 and m7 (#109647)

Branch instruction alignments were not defined for cortex-m85 and
cortex-m7 which misses an optimisation opportunity. With this patch we
see performance improvements as high as 5% on some benchmarks with most
around 1%.
