all: tests, tweaks for lazy extension decoding

Add a test to confirm that extensions are lazily decoded when we expect.

Drop the UnmarshalDefaultResolver flag. I added it thinking for some
reason that internal/impl couldn't depend on protoregistry; since it can
(and does), it's simpler to just test if the resolver is the expected
value.

Use a default set of options when lazily unmarshaling extensions.
