doc/README.gpt: define partition type GUID for U-Boot environment
When setting aside a GPT partition for holding the U-Boot environment,
having a partition type GUID [1] indicating "Linux filesystem" (as
most tools default to) is somewhat misleading - and there's no other
well-known type GUID that is better suited. So to have a canonical
value to put into the type field, define
3de21764-95bd-54bd-a5c3-4abe786f38a8
to mean a partition holding a U-Boot environment.
This is a v5 namespace-name GUID [2], generated [3] from a namespace
of "25cbcde0-8642-47c6-a298-1a3a57cd256b" and name "U-Boot
environment".
Should future type GUIDs be defined in the context of U-Boot, it's
sensible to use that same namespace GUID.
