freerdp3: align CMake opts and add RDPECAM

Drop/rename obsolete FreeRDP2-era CMake flags for the FreeRDP 3.30.0 package wiring, and add a dedicated BR2_PACKAGE_FREERDP3_RDPECAM toggle that enables CHANNEL_RDPECAM and CHANNEL_RDPECAM_CLIENT with libv4l/libusb dependencies. Enable it in generic-x86_64 config.
