Enable Soong's tradefed_binary to support multi-arch

The original `tradefed_binary_host` in Soong always used the host OS
architecture when writing the `arch` in `test-suite-info.properties`.
This change introduces the `Suite_arch` attribute in
`tradefed_binary_host`, allowing users to specify the architecture
for `test-suite-info.properties`.

Bug: 313535357
Test: 1. Add property of `suite_arch` in the Android.bp
      2. m cts-tradefed
      3. check `test-suite-info.properties` in cts-tradefed.jar
