This PR replaces the descriptor name validation regex with a validation method. This change allows the `System.Text.RegularExpressions` engine to be trimmed away in published apps that do standard protobuf serialization.
There are some other usages of `Regex` in Google.Protobuf, but they in `JsonParser`. They are only included in a published app if `JsonParser` is used.
Another benefit is a slightly faster app startup time. The removed regex was compiled, which has a high-ish fixed cost.

For legal reasons we unfortunately cannot accept any external contributions to
the well-known type protos, so this change reverts the small number of changes
we have received so far.

- Reduce what headers the runtime import needs.
- Remove stale function prototype.
- Move one function to be full scoped to a single file.

For PODs, parse the data before making the NSNumber used for extension
fields.
For messages/groups, create the message first, add it to the object graph,
and balance the retain count before doing the parsing. This ensure if an
error is hit (and a throw happens), the object(s) won't be leaked.
Parsing will always mutates the graph, so yes this includes more mutations
in failure cases, but other fields could always be modified before the
bad data is encountered. But even then, that edge case *only* apples to api
users that are explicitly *merge* (-mergeFrom...), the majority of the calls
are to +parseFromData:error:, so the entire graph is released on failure.

The validation is done at the highest point so if a sub message is what
goes over the limit it is caught at the outer message, thus reducing the
impact on the serialization code.

Add a helper to put the logic in one place in the file.
Ensure all places that read messages also do the 2GB check for message size.

The last attempted (rolled back) resulted in changes in visible behavior:
- It consumed a recursion depth on the input stream (wrong)
- It resulted in different error codes for some malformed/truncated data.

- The support for CI has been removed (no longer needed)
- Update some of the testing targets
- Removed some lesser used options (to simplify)

This is done in basically the same way the C++ does this.
It was tested locally be putting `#error` directives in the pre-generated
sources and running the bazel build (it worked).

Every where the script is invoked from protoc is already built, and this more
follows the model used by similar scripts for other languages.
