McuSupport: Identify MinGW toolchain

QtMCUs will support MinGW toolchain for Windows desktop platform,
so MinGW toolchain needs to be identified.

If the default toolchain or a user configured one is a correct
MinGW toolchain, it would be selected. If not, a proper toolchain
would be picked up from the registered toolchains in Qt Creator.
