Split third_party/local_proto_mirror into separate repositories.

At present local_proto_mirror is a grab-bag of separate repositories,
however in preparing for bazel 9 modules, some of these need to be
exposed under different names, and we may use some from the bcr,
so splitting it into per-repository local overrides makes sense.

local_googleapis_imports
   imports.bzl

local_protoc_gen_validate
    validate/validate.proto
    bazel/pgv_proto_library.bzl

local_rules_go:
    proto/def.bzl
    proto/compiler.bzl
    go/def.bzl

local_opencensus_proto:
    opencensus/proto/resource/v1/resource.proto
    opencensus/proto/trace/v1/trace.proto
    opencensus/proto/trace/v1/trace_config.proto
