sql: issue GetRequests from SQL when possible

Previously, SQL unconditionally emitted ScanRequests for every read that
it produced, even if we were completely sure that the scan could contain
only a single key that was fully known at request time.

This was less efficient than necessary, because ScanRequests cause the
KV layer to do more work than GetRequests.

Here are the reasons why GetRequests are more efficient:

- MVCCGet, unlike MVCCScan, is able to use a prefix iterator, which
  allows it to make use of RocksDB/Pebble bloom filters. There may also
  be other wins at the storage layer, like avoiding prefetching
- various data structures have optimizations and fast-paths for
  single-key operations (e.g. timestamp cache, latch manager, refresh
  span tracking)
- various code paths are simpler in the point operation case
- a point operation implies only needing a single key allocation instead
  of a start and end key allocation
- a point operation implies only needing to return up to a single
  result, which means that we can avoid some indirection in various
  places
- A scan over a span that has at most 1 key, but does not know it, needs
  to iterate over all the versions (or eventually do a second expensive
  seek), looking for the non-existent next key in the span. A Get can do
  a single seek, read the key, and be done.

Release note (performance improvement): SQL will now emit GetRequests
when possible to KV instead of always emitting ScanRequests. This
manifests as a modest performance improvement for some workloads.
