Infers custom vendor partitions.
Rather than hardcoding a list of allowed vendor partitions, we accept
anything in the vendor target files that is not a framework partition.
Also extend support for inferred misc_info keys when the device uses
SYSTEM/product or SYSTEM/system_ext.
Test: test --host releasetools_test
Test: Use to merge a device with a custom IMAGES/*.img in the vendor
build, and SYSTEM/system_ext in the system build.
