Replace all uses of `FSTSerializerBeta` in `remote_objc_bridge.{h,mm}` with the C++ `Serializer`. Also, make most of `remote/` sources pure C++ and remove no-longer-used methods in `FSTSerializerBeta`. All integration tests pass, under Address Sanitizer as well.
Unfortunately, pretty-printing is still delegated to Objective-C, so that `remote_objc_bridge.mm` still has to be an Objective-C++ source (and which prevents inlining `remote_objc_bridge` into the streams).
#no-changelog Will add a changelog entry when local serializer is ported, too.
* Rationalize input validation exceptions and assertions
... under a single ThrowHandler concept. This makes it possible to set
an alternative ThrowHandler in our C# bindings that properly translates
input validation exceptions to the correct .NET exception types.
* Rename api/input_validation.h to util/exception.h
* Reimplement util/hard_assert.h in terms of util/exception.h
* Rewrite Document-related classes as a polymorphic value type
* Pass ObjectValue without rvalue references
* Rename HasLocalMutations
* Port C++ users to new Documents
* Port FSTDocumentTests to C++
* Port FSTDocumentSetTests to C++
* Migrate DocumentMap and DocumentSet to C++ Document
* Migrate test helpers
* Delete FSTDocumentSetTests
* Delete FSTDocumentTests
* Mechanical changes to use C++ Document
* Updates to the project file
* Nontrivial test updates
* Remove FSTTestDeletedDoc
* Remove FSTTestUnknownDoc
* Remove FSTDocument
* Convert usage of FSTDocument to C++ Document
* Fix Serializer usage of Documents
* Drop acknowledged mutations in schema migration (#1818)
Drop acknowledged mutations in schema migration as part of removing held write acks.
Port of firebase/firebase-js-sdk#1149

Extract useful bits of FSTUserDataConverter for use in C++:
* Migrate FSTParsedSetData to core::ParsedSetData
* Migrate FSTParsedUpdateData to core::ParsedUpdateData
* Migrate FSTParseContext to core::ParseContext
* Split ParseAccumulator out of ParseContext to make ownership easier
Also:
* Remove dead code (handled in parseSentinelFieldValue)
* Flatten App/iOS/Supporting Files into the parent
* Move all Firestore files to Objective-C++
* Update project file references
* Don't use module imports from Objective-C++
* Use extern "C" for C-accessible globals
* Work around more stringent type checking in Objective-C++
* NSMutableDictionary ivars aren't implicitly casted to NSDictionary
* FSTMaybeDocument callback can't be passed a function that accepts
FSTDocument
* NSComparisonResult can't be multiplied by -1 without casting
* Add a #include <inttypes.h> where needed
* Avoid using C++ keywords as variables
* Remove #if __cplusplus guards
