Prepare for migration from ts_library to ts_project

With the upcoming migration from rules_nodejs to rules_js, I am
changing all the `ts_library` targets to become `ts_project` targets.

This patch introduces an alias for a NOP effect. A future patch will
switch the actual implementation.

I am leaving the scouting directory alone because all the build rules
will change completely. They will use Angular-specific rules.
