intel/aubinator_error_decode: Allow for more sections

Error states coming from actual Vulkan applications tend to have fairly
long command buffers and lots of chained batches.  30 total BOs isn't
nearly enough.  This commit bumps it to 256, makes some things use the
actual number of sections instead of the #define, and adds asserts if we
ever go over 256 sections.
