This patch-set adds Ext4Pkg, a package designed to hold various drivers and
utilities related to the EXT4 filesystem.

Right now, it holds a single read-only UEFI EXT4 driver (Ext4Dxe), which consumes the
DISK_IO, BLOCK_IO and DISK_IO2 protocols and produce EFI_FILE_PROTOCOL and
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL; this driver allows the mounting of EXT4 partitions and
the reading of their contents.

A relevant RFC discussion, which includes a more in-depth walkthrough of EXT4 internals and
driver limitations is available at https://edk2.groups.io/g/devel/topic/84368561.

This patch set is version 3 and attempts to address issues raised by the
community in v2's code review.
