configs: mt8183: android: add A/B slot select support
This adds the u-boot environment support for Android A/B [1], such as:
- slot selection on early startup (from /misc)
- skip_initramfs commandline depending on boot mode
All A/B related code is guarded around CONFIG_CMD_AB_SELECT, and is not
activated.
Note: the android_ab_slot env variable will always be defined, but is
unused in the case of legacy ota support.
