  [clang][dataflow] Add analysis that detects unsafe accesses to optionals

This commit reverts e0cc28dfdc67105974924cce42bb8c85bd44925a and moves
UncheckedOptionalAccessModelTest.cpp into clang/unittests/Analysis/FlowSensitive,
to avoid build failures. The test will be moved back into a Models subdir
in a follow up patch that will address the build configuration issues.

Original description:

Adds a dataflow analysis that detects unsafe accesses to values of type
`std::optional`, `absl::optional`, or `base::Optional`.
