Add support for a file listing expected package to objc prefixes for validation.

Signed-off-by: Dan O'Reilly <oreilldf@gmail.com>

- Add a env var to pass a set of expected prefixes for validation.
- Report warnings/errors based on the expected prefixes vs. the data in the files compiled.
- Use some helpers from common directory.

Fixed several Ruby conformance test cases through upb update.

Allow public access to descriptor.proto as a dependency.

With this in place, generating APIs on github.com/google/googleapis works - previously annotations.proto failed.
Currently there's no access to the annotations (stored as extensions) but we could potentially expose those at a later date.

Link runtime statically for VS build

Revert "Add packFrom, unpackTo and is in google.protobuf.Any."

This reverts commit 7366efd8.

Still some discussion about the api to expose the helpers with.

Update GPBWellKnownTypes.m

More TODOs done.

- Removed a TODO without change in DescriptorPool.LookupSymbol - the TODOs were around performance, and this is only used during descriptor initialization
- Make the CodedInputStream limits read-only, adding a static factory method for the rare cases when this is useful
- Extracted IDeepCloneable into its own file.

Implement Keys and Values as views in MapField

 Make FieldDescriptor.IsPacked work appropriately.

Remove our own version of MakeTag now that the main one is fixed.

This is a bit of a grotty hack, as we need to sort of fake proto2 field presence, but with only a proto3 version of the descriptor messages (a bit like oneof detection).
Should be okay, but will need to be careful of this if we ever implement proto2.
