* [tests] Move linker tests to match introspection directory layout.
Move linker tests to match introspectio directory layout: tests/linker/ios and
tests/linker/mac instead of tests/linker-ios and tests/linker-mac.
This creates a logical place for shared linker files (tests/linker).
* [tests] Fix path to GuiUnit_NET_4_5.csproj in sln as well.
This is the path used to find referenced projects when building Classic.
Fixes this build problem:
warning: Referenced project 'GuiUnit_NET_4_5' not found in the solution.

Make sure to package the linker tests when packaging XM tests (this broke
recently because the dontlink tests were moved).
Fixes this problem when running the packaged tests:
