[analyzer][NFC] Trivial refactoring of region invalidation (#102456)

This commit removes `invalidateRegionsImpl()`, moving its body to
`invalidateRegions(ValueList Values, ...)`, because it was a completely
useless layer of indirection.

Moreover I'm fixing some strange indentation within this function body
and renaming two variables to the proper `UpperCamelCase` format.
