Peter Dillinger b234a3f569 Improve data block construction performance (#9040) 
Summary:
... by bypassing tracking of last_key in BlockBuilder when
last_key is already known (for BlockBasedTableBuilder::data_block).

I tried extracting a base class of BlockBuilder without the last_key
tracking at all, but that became complicated by NewFlushBlockPolicy() in
the public API referencing BlockBuilder, which would need to be the base
class, and I don't want to replace nearly all the internal references to
BlockBuilder.

Possible follow-up:
* Investigate / consider using AddWithLastKey in more places

This improvement should stack with https://github.com/facebook/rocksdb/issues/9039

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9040

Test Plan:
TEST_TMPDIR=/dev/shm/rocksdb1 ./db_bench -benchmarks=fillseq -memtablerep=vector -allow_concurrent_memtable_write=false -num=50000000
Compiled with DEBUG_LEVEL=0
Test vs. control runs simulaneous for better accuracy, units = ops/sec

Run 1: 278929 vs. 267799 (+4.2%)
Run 2: 281836 vs. 267432 (+5.4%)
Run 3: 278279 vs. 270454 (+2.9%)

(This benchmark is chosen to have detectable signal-to-noise, not to
represent expected improvement percent on real workloads.)
