This allows users to override the fake SDK with a real one using https://bazel.build/rules/lib/globals/module#override_repo.
Without this change, it is impossible for a project that depends on googletest as a `bazel_dep` to build tests using the "real" Fuchsia SDK, because any references to `@fuchsia_sdk` within googletest `BUILD.bazel` files unconditionally resolve to the "fake" Fuchsia SDK. With this change, if you have the real Fuchsia SDK declared in your `MODULE.bazel`, you can add the following lines to coerce googletest to use the real Fuchsia SDK as well:
fake_fuchsia_sdk_extension =
use_extension("@com_google_googletest//:fake_fuchsia_sdk.bzl", "fuchsia_sdk")
override_repo(fake_fuchsia_sdk_extension, "fuchsia_sdk")

Since Fuchsia engineers rarely work within this repo, initialize a lightweight fake @fuchsia_sdk repo rather than distributing the Fuchsia SDK here.
Tested locally via `bazel query --[no]enable_bzlmod "deps(set(//googletest/test:gtest_all_test))"` (#4472)
