common: android_bootloader: Abandon preload data when boot_partition changed

1. Handle the case: "avb lock + (vbus = 0) + recovery key pressed".
2. Need to clean preload data, when boot_partition change.
3. Saved boot_partition shouldn't have _a or _b suffix because

It also can use to enable or disable the verification
function by using avb_user_verity_set in the file
avb_user_verify.c.

Since we use fastboot to program our firmware,
some necessary function is provided to fastboot
to get useful information, like slot number, current
slot and so on.

Some functions in the avb_ops_user.c, like read_rollback_index,
depend on the OpteeClientTest.h.
