rtw89: 8852c: add 8852ce to Makefile and Kconfig

This initial vesion is usable now. It can support STA, AP and monitor
modes, so we can add 8852ce to Kconfig and Makefile.

We are still working on some features, such as deep power save, and BT
coexistence. But, this version still can have a good WiFi-only performance
already, and will continue to fine tune power consumption.
