sql/logictest: add logictest for all expected 1PC txn statements

First commit from cockroachdb#41324.

We expect a selection of simple single-statement mutations to hit the
"1-phase commit" transaction fast-path. cockroachdb#41320 demonstrated how critical
this is, as regressions here can cause major (> 50%) performance hits to
benchmarks and user workloads. This commit adds a logic test to validate
that these statements continue to hit this fast-path.

Release justification: Testing only.

Release note: None
