Sometimes features are removed from `Features.def`, but they are not removed from the test files. The compiler ignores every feature that does not exist. This leads to removed features still being tested, and with the introduction of #76740, `REQUIRED:`. Modify the code that generates the active feature set for testing to also generate the set of existing features, and pass this list of existing features to the verifier script. If a feature is trying to be activated and does not exist, the verifier will warn the user. - `SwiftParser` feature was renamed `ParserASTGen`, but some tests were using both spellings. Remove the mentions of `SwiftParser` in the tests. - `ImportObjcForwardDeclarations` was spelled with upper case `C` in a couple of tests. Fix it so the matching is easier. - `TransferringArgsAndResults` was an experimental feature that was removed. - Ignore the usage of inexisting feature in `swift-export-as.swift` because it seems to be what the test is actually testing. - Ignore the test `availability_define.swift` because it tests the pseudo-feature `AvailabilityMacro=` which is not part of `Features.def`.
