When a framework is linked to a target by its full path and that
framework is located in one of the implicit framework search directories,
CMake 3.18.5 and earlier discarded that path.
ce2dee9e (Xcode: Don't add framework as -framework argument in
linker info list, 2020-09-28) introduced a regression which resulted in
the framework path always being added to the search path even if it
matched one of the implicit search paths. This broke the ability to do
device and simulator builds from the same configured project.

Fixes: #21678
