Add build properties to enable casefold and prj_quota

This adds the ability to format f2fs and ext4 in a way that supports
casefolding and project quotas. Project quotas require wider inodes, and
thus cannot be enable apart from at build time. Casefolding can be
configured with f2fs.fsck/tune2fs later.

Both features are enabled via inheriting emulated_storage.mk in the
device.mk
