fix(ivy): prevent templateOverrides from causing infinite loop (#29402)

Previously, the transitive scope calculation could lead into re-compiling
the same module multiple times. This fix ensures we cannot get into this loop.
It should be fixed more completely (e.g. more cases) once FW-1178 is resolved.
