OvmfPkg/EnrollDefaultKeys: refresh INF file

Bump INF_VERSION to the latest edk2 INF specification.

Regenerate FILE_GUID to distinguish this application from downstream-only
versions.

Remove the VALID_ARCHITECTURES comment as there is nothing ISA or platform
specific in the application.

Ensure all sections apart from [Defines] are alphabetically sorted.
