igt/gem_ctx_isolation: Check isolation of registers between contexts

A new context assumes that all of its registers are in the default state
when it is created. What may happen is that a register written by one
context may leak into the second, causing mass confusion.

v2: Extend back to Sandybridge (etc)
v3: Check context preserves registers across suspend/hibernate and resets.
v4: Complete the remapping onto the new class:instance
v5: Not like that, like this, try again to use class:instance
v6: Prepare for retrospective gen4 contexts!
v7: Repaint register set name to nonpriv, as this is what bspec calls the
registers that are writable by userspace.
v8: Fix a typo for LRM on gen8
