[FIR] Search expect for actual only in dependsOn dependencies

Before this commit, the expect-actual resolver could find expects in
regular dependencies

Note: The appeared `VIRTUAL_MEMBER_HIDDEN` in
compiler/fir/analysis-tests/testData/resolveWithStdlib/multiModule/FakeOverrides.kt
isn't caused by my change. It's caused by fixing the testData dependency
syntax notation.

The testData improperly used regular dependency syntax notation, while
it should have been using dependsOn

Before:
    Regular dependency syntax notation

    // MODULE: androidMain(commonMain)

After:
    dependsOn dependency syntax notation

    // MODULE: androidMain()()(commonMain)
