Add rust_test and rust_test_host.
* Rust tests are like binary files compiled with --test.
New test.go follows binary.go code patterns and reuses
some code in binary.go.
* Generate one test per source file as testPerSrc in cc/test.go.
The "all tests" variation feature of cc/test.go is not copied yet.
Fix some Stem and SubName settings to make testPerSrc work.
* Move cc.CheckDuplicate to android.CheckDuplicate,
which is now shared by cc and rust.
* Refactor tests in binary_test.go and add new test_test.go.
Bug: 140938178
