gem_list_engines() should list engines correctly on platforms prior to
MTL. But at present it doesn't, it only supports MTL, and it skips on the
'igt_require(IS_METEORLAKE)' check for prior platforms. Fix this by
modifying gem_engine_to_gt_map() to return gt 0 for prior platforms,
because the only multi-gt platform supported at present in MTL.

Fixes: d2f39ce8186a ("lib/i915/gem_engine_topology: list engines specific to gt")
