Verifying SILGen causes `loadAllMembers` to be run, which in turn ends
up actually creating the parent PBD of each `VarDecl` in this test.
Without verification, we never deserialize that PBD and thus end up with
`class` instead of `static` as we should. That's incorrect, but it's an
existing failure (rdar://105239467).

Solver based results are fast within a function, where the `ASTContext`
can be re-used. But it is significantly slower than the AST based
results when outside of a function. Instead of using solver based as the
primary results, only use them as a fallback for when AST based fails.

Re-enable `static_vs_class_spelling.swift` - it was just missing the
`-target` in the `sourcekitd-test` lines.
While here, cleanup all the cursor info tests that used `split_file` to
use `split-file` instead.
Resolves rdar://105287822.
In these cases the solver-based and AST-based cursor info differed in their results. Fix the AST-based cursor info to return the correct results and add test cases to make sure the solver-based implementation doesn’t regress them.
