Some commits (https://github.com/masemoel/device_xiaomi_picasso/commit/77b867ca9edf7fb9ec399aa0f747070d1e40ca26) discard force enable Volte.

It seems that CarrierConfig was added but CarrierConfig in overlay was not configured in device.mk

Fixed by refferring to https://github.com/VoidUI-Devices/device_xiaomi_sm8250-common/commit/d7cb8df03a1852a9c0c2dd8b3f4ab9a0cb364a6e to patch ims.apk
