Move Crashdump to OemCrashdump

All other Oem Schemas start with Oem.
This is used by the update_schemas.py to determine an Oem
schema and is a reasonable requirement for Oem schemas.

https://github.com/openbmc/bmcweb/blob/a3268f98f308ca7c8660b1ace44d5b9a40be204b/scripts/update_schemas.py#L43

Tested: Ran the validator against this change on a Witherspoon
        with BMCWEB_ENABLE_REDFISH_CPU_LOG enabled and OemCheck
        true. Validator passed. Might be worth running on a
        system that actually uses BMCWEB_ENABLE_REDFISH_CPU_LOG.
