Flip cc_test to use the Starlark version.

NOTE: This does not change the use of platform/toolchains based cc_test.

`env` attribute now handles location / makevar expansion.

RELNOTES:
Switch cc_test implementation to Starlark. Note: cc_test will now
link statically when _targeting_ Windows regardless of host platform (rather
than always linking statically when Windows is the _host_).

Additionally, the behavior of env_inherit differs--notably the inherited
environment overrides the fixed environment.
