pb: Update Flags

[DelightReza]

• Use PB_ENABLE_PATCH_AVB2_CHECK := true to enable Patch AVB 2.0 check by default

• Use PB_ENABLE_DM_VERITY_CHECK := true to enable Deactivate DM-Verity Check by default

• Use PB_ENABLE_SKIP_TREBLE_COMP_CHECK := true to enable Skip Treble Compatibility Check by default

Looks good but we need to make sure that all devices adapt to these flags.

Mostly devices need to disableed it by default, for those who want to enable can use flags😂
