1ef02bb1 - [mypyc] Fix using values from other modules that were reexported (#7496)

[mypyc] Fix using values from other modules that were reexported (#7496) There are a couple parts to this: * Compile module attribute accesses by compiling the LHS on its own instead of by loading its fullname (which will be what mypy thinks its source is) * Only use the static modules if they have actually been imported Fixes mypyc/mypyc#393.
