MdePkg: Add DECLARE_LENGTH opcode of dependency expression

To avoid messy parsing of the Depex section of a Capsule, it would
be a lot easier for everyone involved if we preceded the Capsule Depex
Section with a length declaration. It provides simple bounds checking
to avoid having to parse the op-codes, but in the case of a malformed
depex being parsed, avoid other issues which can be messy.
