[Intel-gfx] [PATCH v6 i-g-t 3/3] tests/i915/query: Query, parse and validate the hwconfig table

From: Rodrigo Vivi <rodrigo.vivi at intel.com>
Newer platforms have an embedded table giving details about that
platform's hardware configuration. This table can be retrieved from
the KMD via the existing query API. So add a test for it as both an
example of how to fetch the table and to validate the contents as much
as is possible.
