build: remove compile build variable (#34280)

Remove the remaining check for compile build variable in the ng_module
rule.  Now that components is no longer relying on this build variable
we can safely remove it from our repository.

We will leave the remaining check for if the compile build variable is
used within our own repo, with plans to remove it in a couple months.
It is being kept in place to ensure that uncommitted local scripts for
our own development that we have locally, kill error as expected if
they still reference the compile build variable.
