Automated rollback of commit 363413110f3a63a11d900864be1852adbaed2899.

*** Reason for rollback ***

Breaks //src/test/shell/bazel:bazel_bootstrap_distfile_test:

*** Original change description ***

Add a new toolchain type for c++.  In order to do this, PlatformConfiguration is made a legal configuration fragment for every rule class.

Add a default "dummy" c++ toolchain to prevent resolution errors when legacy toolchain selection logic is used.  Add toolchain mocks to java and shell tests.
