Mohammad El-Shennawy 637f8c4db7 MDEV-21543: Speed up VARCHAR pad space handling 
- Scoped partial optimization for MDEV-21543 improving
PAD SPACE collations for multibyte character sets in
HA_KEYTYPE_VARTEXT1.
- This keeps the old behavior for other cases until
MDEV-38712 is resolved.
- Benchmark: see zulip topic in the PR description
- Results:
- ~3.1% lower wall-clock time
- ~2.1% fewer CPU cycles
- ~0.5% fewer retired instructions
- ~0.7% fewer branch mispredictions
