Expose TocFile via CcInfo

To reflect what's provided in SharedLibraryInfoProvider

Move the logic for identifying the toc file into Starlark
instead of the Soong Go code.

Adapt TestGetCcInfoParseResults to expect the toc as well.

Test: build/bazel/cquery/request_type_test.go:TestGetCcInfoParseResults
Test: cc/library_test.go:TestCcLibrarySharedWithBazel
Test: build/bazel/ci/mixed_{libc,droid}.sh
