(#8174) Allow defines to reference topscope

Because the compiler re-assigned the topscope, looking up topscope vars
or facts from a defined resource type was causing deprecation warnings
when it should not be. By cherry-picking commits
b02aa930a03a282588e81f65e14f47a138a4b9f0 and
c995be16bc9e3ad8dbad9d21b49df76de5b72ea9 the topscope is no longer
re-assigned and so defined resource types can now lookup these kinds of
variables without problem.
