BEGIN_PUBLIC
Doing a transition to the exec platform in rule-based toolchains was causing unusual behaviors when attempting to restrict compatibility. This changes most of the toolchain rules to be evaluated from the target platform configuration, only transitioning to the exec configuration when explicitly requested.

BEGIN_PUBLIC
Refactor action sets for consistency and simplicity
* Remove the "CC" prefix on some of the actions, as we're already within the scope of rules_cc.
* Remove the "all" prefix, since the plural "actions" should already imply this.
* Ensure all action types sets end with "_actions"
* Refactor some action type sets to be constructed from other (eg. link actions = link executables + link dynamic libraries).
* Remove the redundant "all_compile_actions", since it was equivalent to "all_cc_compile_actions"
