Lionel Landwerlin 36c043e2eb intel: move debug identifier out of libintel_dev 
The debug identifier is put into the captured buffers for error
capture. This helps us figure out what version of the driver people
are running when encountering a GPU hang. This identifier has the
git-sha1 + driver name.

libintel_dev is also a dependency of the compiler so any change to the
git-sha1 also triggers recompile which we want to avoid.

This changes moves the debug identifier to src/intel/common which
drivers already depend on, so the compiler is not affected anymore.

José Roberto de Souza 90e38bbb3b intel/tools/error_decode: Parse Xe KMD error dump file 
There is more to do but this is able to parse batch buffers, including
fetch and parse other bos like shader programs.

Some functions used by read_i915_data_file() could be shared with Xe
so I have moved those to aubinator_error_decode_lib.c/h.

In the code path without arguments it tries 3 different paths and error

error messages are irrelevant.

For the code path with arguments is similar, as it already have a

happened to be there.

Also, properly pass the `from_ring` parameter to gen_print_batch()
so that decoding doesn't stop once MI_BATCH_BUFFER_END is
encoutered.
