- Update `transfer` and `diagnose` to take `const CFGElement *` as input in `Analysis/FlowSensitive/Models/UncheckedOptionalAccessModel`.
- Update `clang-tools-extra/clang-tidy/bugprone/UncheckedOptionalAccessCheck.cpp` accordingly.
- Rename `runDataflowAnalysisOnCFG` to `runDataflowAnalysis` and remove the deprecated `runDataflowAnalysis` (this was only used by the now updated optional check).

Make the types of the post visit callbacks in `transferBlock` and
`runTypeErasedDataflowAnalysis` consistent.

Followup to D128352. This patch pulls the `NoopLattice` class out from the `NoopAnalysis.h` test file into its own `NoopLattice.h` source file, and uses it to replace usage of `SourceLocationsLattice` in `UncheckedOptionalAccessModel`.

Followup to D127898. This patch updates `bugprone-unchecked-optional-access` to use the new `diagnoseCFG` function instead of just looking at the exit block.
A followup to this will update the optional model itself to use a noop lattice rather than redundantly computing the diagnostics in both phases of the analysis.

This check verifies the safety of access to `std::optional` and related
types (including `absl::optional`). It is based on a corresponding Clang
Dataflow Analysis, which does most of the work. This check merely runs it and
converts its findings into diagnostics.
