MdeModulePkg: Initial UDF/ECMA-167 file system support

This patch introduces UDF file system support in EDK2. All block devices
that support BlockIo and DiskIo protocols and contain a valid UDF file
system - as specified by OSTA Universal Disk Format (revisions 1.02
through 2.60) - will be installed EFI_SIMPLE_FILE_SYSTEM_PROTOCOL to
provide access to underlying file system.

File system operations on regular, directory and symlink files are
supported.
