BareMetal: Fix auto detection of SDCC toolchain on Windows

Browse Source 
The SDCC toolchain package can be provided as 32-bit
or as 64-bit installer. If the SDCC 64-bit package
will be installed on the 32-bit Windows, then it will
not be found in the system registry, because we use
the QSettings::NativeFormat. So, we need to check the
data for the 32-bit and 64-bit registry sequentially.
