During .new decode, there are several places where strchr is used.
We remove these by generating the values that are needed.

Once we have generated the proper values, we no longer need
op_regs_generated.h.inc.  We remove the script that generates it as
well as the code in meson.build

We also remove the script and meson.build code that creates
shortcode_generated.h.inc.  The data structure that includes it is
not used.

We remove hex_common.read_attribs_file.  The Python data structures built
during this step are not used.
