crash_collector: Handle compressed i915_error_state for chrome crashes

i915_error_state was previously truncated by debugd,
and will be compressed in the future to prevent that.

Because of compression, it will now be received in base64 format,
so to reduce it's size, decode it back.

Also, use xz compression, since it's more compact.
The second compression is a preparation for adding task states to the logs.
