Add some settings for diagnostics on type
Add some settings for diagnostics on type

Some settings are not exposed in the settings UI:
purescript.noFsDiagnostics
purescript.revertExternsAndCacheDb
purescript.cacheDbRevertTimeout
purescript.diagnosticsCodegen

These are either more experimental or have a dependency on a compiler fork.
