CMake: remove test for alloca for the global config
We don't test for this anywhere in qtbase except for the qmake check (and qmake doesn't use alloca() anywhere). There are a couple of uses of alloca() itself in qtbase, but they are all in platform-specific code (android and qnx platform plugins) or third-party content (sqlite and imgui). The uses of this alloca() test in qtdeclarative have been removed too (it still uses alloca() but has local tests).
