BaseTools/FirmwareStorageFormat: Fix FV ext entry struct factory functions
The Refine_FV_EXT_ENTRY_OEM_TYPE_Header() and
Refine_FV_EXT_ENTRY_GUID_TYPE_Header() functions incorrectly return
an instantiation attempt of the local class with `Structure` as an
argument (e.g., `return ClassName(Structure)`) instead of returning the
class itself (e.g., `return ClassName`).
This causes FMMT to fail with:
"expected EFI_FIRMWARE_VOLUME_EXT_ENTRY instance, got
_ctypes.PyCStructType"
When processing FVs that contain ext header entries of type 0x01
(OEM Type) or type 0x02 (GUID Type, used for FV UI Name when
FvNameString = TRUE).
Fix by returning the class directly, matching the pattern used by
Refine_FV_Header() which correctly returns the class for subsequent
.from_buffer_copy() calls.
