anv: increase ANV_MAX_STATE_SIZE_LOG2 limit to 1 MB

Fixes crash in dEQP-VK.ubo.random.all_shared_buffer.48 due to a
fragment shader code bigger than 128 kB.

This patch increases the allocation size limit to 1 MB.

v2:
- Increase it to 1 MB (Jason)
- Increase device->instruction_block_pool allocation size in
  anv_device.c (Jason)
