drm/i915/gt: Explicitly clear BB_OFFSET for new contexts
Even though the initial protocontext we load onto HW has the register
cleared, by the time we save it into the default image, BB_OFFSET has
had the enable bit set. Reclear BB_OFFSET for each new context.
Testcase: igt/i915_selftests/gt_lrc
v2:
Extend it for gen8.
v3:
BB_OFFSET is recorded per engine from Gen9 onwards
