Peter Dillinger e92a0ed040 Optimize & clean up footer code (#9280) 
Summary:
Again, ahead of planned changes in https://github.com/facebook/rocksdb/issues/9058. This change improves
performance (vs. pre-https://github.com/facebook/rocksdb/issues/9240 baseline) by separating a FooterBuilder from
Footer, where FooterBuilder includes (inline owns) the serialized data
so that it can be stack allocated.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9280

Test Plan:
existing tests + performance testing below

Extreme case performance testing as in https://github.com/facebook/rocksdb/issues/9240 with

    TEST_TMPDIR=/dev/shm/ ./db_bench -benchmarks=fillseq -memtablerep=vector -allow_concurrent_memtable_write=false -num=30000000

(Each is ops/s averaged over 50 runs, run simultaneously with competing
configuration for load fairness)
Pre-https://github.com/facebook/rocksdb/issues/9240 baseline (f577458): 436389
With https://github.com/facebook/rocksdb/issues/9240 (653c392): 417946 (-4.2% vs. baseline)
This change: 443762 (+1.7% vs. baseline)
