OptionRomPkg: .dsc fixes for ARM/AARCH64 and USB drivers

Drivers under OptionRomPkg wouldn't build standalone, since ARM and
AARCH64 were missing from SUPPORTED_ARCHITECTURES. So add them.
Also, add some compiler libraries needed for ARM/AARCH64 GCC
toolchains (CompilerIntrinsicsLib and BaseSwStackCheckLib).

Also, the UsbNetworking drivers were not listed under [Components],
so failed to build standalone. This patch adds them.
