Subject: tools/intel_reg: Add reading and writing registers through engine

Add option to specify engine for register read/write operation.
If engine is specified, use MI_LOAD_REGISTER_IMM and MI_STORE_REGISTER_IMM
to write and read register using a batch targeted at that engine.

v2: no MI_NOOP after BBE (Chris)
v3: use modern engine names (Chris), use global fd
v4: strcasecmp (Chris)
v5: use register definition format for engine (Jani)
