Migrate to Bzlmod for managing external dependencies

[meteorcloudy]

With future Bazel LTS versions, Bzlmod will become the default system for external dependencies management.

Please consider migrating all your external dependencies in WORKSPACE to MODULE.bazel

For more information, please check bazelbuild/bazel#18958

Looks like only two tests failing:

//src/tools/javatests/com/google/devtools/build/android/sandboxedsdktoolbox/apidescriptors:ExtractApiDescriptorsCommandTest FAILED in 3 out of 3 in 0.4s
//src/tools/javatests/com/google/devtools/build/android/sandboxedsdktoolbox/sdkdependenciesmanifest:GenerateSdkDependenciesManifestCommandTest FAILED in 3 out of 3 in 0.5s

We need to use the Java runfiles library at

rules_android/src/tools/javatests/com/google/devtools/build/android/sandboxedsdktoolbox/apidescriptors/ExtractApiDescriptorsCommandTest.java

Lines 39 to 42 in 5f96907

	JAVATESTS_DIR.resolve(
	Path.of(
	"com/google/devtools/build/android/sandboxedsdktoolbox",
	"apidescriptors/testlibrary/libtestlibrary.jar"));

Hmm, I thought that all tests under //src/tools were being run in BazelCI already (which should include a bzlmod config): https://github.com/bazelbuild/rules_android/blob/main/.bazelci/presubmit.yml#L7

Curious that there would be tests failing still.

We're 100% on bzlmod now, closing this.
