For consistency with other options types in the protobuf module, make
the test function a method of the options.
Drop the ExtensionTypes option and just look up the extension types to
test with in the provided resolver.

Rename build tag "proto1_legacy" -> "protolegacy"
to be consistent with the "protoreflect" tag.
Rename flag constant "Proto1Legacy" -> "ProtoLegacy" since
it covers more than simply proto1 legacy features.
For example, it covers alpha-features of proto3 that
were eventually removed from the final proto3 release.

Change protoiface.ExtensionDescV1 to implement protoreflect.ExtensionType.
ExtensionDescV1's Name field conflicts with the Descriptor Name method,
so change the protoreflect.{Message,Enum,Extension}Type types to no
longer implement the corresponding Descriptor interface. This also leads
to a clearer distinction between the two types.
Introduce a protoreflect.ExtensionTypeDescriptor type which bridges
between ExtensionType and ExtensionDescriptor.
Add extension accessor functions to the proto package:
proto.{Has,Clear,Get,Set}Extension. These functions take a
protoreflect.ExtensionType parameter, which allows writing the
same function call using either the old or new API:
proto.GetExtension(message, somepb.E_ExtensionFoo)

This implements generation of and reflection support for weak fields.
Weak fields are a proto1 feature where the "weak" option can be specified
on a singular message field. A weak reference results in generated code
that does not directly link in the dependency containing the weak message.
Weak field support is not added to any of the serialization logic.

When encountering a type that does not have a MessageInfo, don't assume
that it's a legacy message that doesn't implement proto.Message. Add a
set of test messages exercising this case (panics prior to the
internal/impl change).

Weak fields are an obsolete proto1 feature. They have been superseded
by extensions. However, some vestigial support for weak fields does
remain, mostly as Google-internal patches. (They aren't exciting;
extensions really do everything weak fields do in a cleaner and
more portable fashion.)
At the moment, the only visible impact of marking a field [weak=true]
is to exclude it from "internal/fileinit".FileBuilder.DependencyIndexes.
We want to preserve that behavior just in case we ever do add full weak
field support here.
Extend fileinit to look up message descriptors for weak fields in the
global registry. If the descriptor cannot be found, use a placeholder
instead.
Remove special-case handling of weak fields in the impl package. The
code generator doesn't do anything special for them, so they can be
treated as any other field.
