fix(types): enable TypeScript libCheck & resolve type conflicts (inve…

…rtase#4306)

* chore: enable TypeScript libcheck & remove "dom" lib
    "dom" conflicts with @types/react-native
* chore: add react types (referenced by admob types)
* refactor(types, app): move "app" exports to top-level exports, rather than module declarations with namespace extensions
* refactor(types): use top-level exports for module types, rather than declarations
* refactor(types): for JSON config, augment existing `ReactNativeFirebase` namespace from /app
    Re-exporting the namespace causes collision issues -- tramples previous values rather than merging
* fix(types, admob): Use string-indexing rather than dot-notation for referring to interface keys
* fix(types, analytics): convert missing interface to `any`
* fix(types, database): missing `value` type (treated as 'any')
* fix(types, dynamic-links): fix dynamic-links `onLink` function type
    "Function" is not generic
* fix(types, firestore): add missing generic to Promise type
    Keep current behavior with `any`
* fix(types, messaging): remove parameter initializer in typedef 
    Only allowed in implementations
* fix(types, messaging): avoid implicit `any` via `void` return type for `setBackgroundMessageHandler`
* fix(types, ml-vision): import non-ambient types in BarcodeDetectorTypes
* fix(types, ml-vision): import non-ambient types in root module from BarcodeDetectorTypes
* fix(types, ml-vision): repair invalid `extends` use by duplicating inherited key
    Could have Omit<>'ed the incompatible `bounds` key, but duplicating the one inherited key seemed less complex
* fix(types, perf): add void return types to untyped perf methods
* tests(admob): add type override to intentionally-wrong syntax
    Incorrect type is now caught by TS
* tests(types, ml-vision): fix ml-vision test typo, exposed by proper types
    VisionBarcodeFormat.ALL_POINTS does not exist
* chore(website): update typedoc to allow recursive types
    uses new syntax: TSConfigReader
