Tim Düsterhus 0cfc45b667 random: Use branchless implementation for mask generation in Randomizer::getBytesFromString() (#10522) ...

* random: Add `max_offset` local to Randomizer::getBytesFromString()

* random: Use branchless implementation for mask generation in Randomizer::getBytesFromString()

This was benchmarked against clzl with a standalone script with random inputs
and is slightly faster. clzl requires an additional branch to handle the
source_length = 1 / max_offset = 0 case.

* Improve comment for masking in Randomizer::getBytesFromString()
