* Rename testBinaryDecorator to testDecorator
* Add TestProperties
* Add install function for testDecorator to install config files
* Add tradefed.AutoGenRustHostTestConfig
* Depend on new build/make/core/rust_host_test_config_template.xml
and new tradefed.testtype.rust.RustBinaryHostTest class
* Add autogenTemplateWithName in tradefed/autogen.go
to generate config files with customized(mutated) executable name.
* Make rust_test module names more robust and easy to use.
* Use crate name instead of source file name as the Stem
for single source file modules, to match original user
specified output file name in Cargo.toml.
* Do not set up test module SubName when Stem is empty
or when the module name already contains Stem suffix.
That happens when TestPerSrcMutator is disabled or when
there is only one source file with renamed output file name.
* In TEST_MAPPING, references to mutated rust_test modules should be
(1) <module_name> for single source file modules without mutation, or
(2) <module_name>_<crate_name> for single source file modules, or
(3) <module_name>_<source_file_base_name> for multi-file modules.
Bug: 140938178
Test: mm in rust projects, check output test file names

* 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
Test: mm in rust projects, added rust_test and rust_test_host
