Changyu Bi 92ad4a88f3 Small CPU optimization in InlineSkipList::Insert() (#12975 )

Summary:
reuse decode key in more places to avoid decoding length prefixed key x->Key().

Pull Request resolved: https://github.com/facebook/rocksdb/pull/12975

Test Plan:
ran benchmarks simultaneously for "before" and "after"
* fillseq:
```
(for I in $(seq 1 50); do ./db_bench --benchmarks=fillseq --disable_auto_compactions=1 --min_write_buffer_number_to_merge=100 --max_write_buffer_number=1000  --write_buffer_size=268435456 --num=5000000 --seed=1723056275 --disable_wal=1 2>&1 | grep "fillseq"
done;) | awk '{ t += $5; c++; print } END { printf ("%9.3f\n", 1.0 * t / c) }';

before: 1483191
after: 1490555 (+0.5%)
```

* fillrandom:
```
(for I in $(seq 1 2); do ./db_bench_imain --benchmarks=fillrandom --disable_auto_compactions=1 --min_write_buffer_number_to_merge=100 --max_write_buffer_number=1000  --write_buffer_size=268435456 --num=2500000 --seed=1723056275 --disable_wal=1 2>&1 | grep "fillrandom"

before: 255463
after: 256128 (+0.26%)
```
