  [ubsan] Use internal_memcpy to copy ubsan bits size (#121586)

While fetching amounts of bits used to correctly display ubsan value
reinterpret_cast was used, however as noted by Jakub Jelínek in
https://github.com/llvm/llvm-project/pull/96240 discussion it might
cause issues due to potentially unaligned memory access. The patch
addresses this problem.
