dump-consts.py doesn't work anymore

It's referenced in the debugging tips in CONTRIBUTING.md: https://github.com/tenstorrent/tt-metal/blob/main/CONTRIBUTING.md#debugging-tips

When I manually install:

ELF file has no DWARF info.

docopt is a dependency (to parse the command line arguments): pip install docopt.

DWARF information is required for dump-consts. It gets added to the ELF files when -g complier flag is present. The flag was removed in 1837b1f. We should:

• add an env var to add the flag back in -g (TT_METAL_RISCV_DEBUG_INFO)
• improve the message shown by dump-consts.py
• add the above to the documentation

Should we add docopt to our python installation?

[ihamer-tt]

Yes. The last commit is to add it to requirements-dev.txt @tt-dma, let me know if you were thinking of some other env as well.

: Add docopt to dev-requirements

Yeah that's the one, thanks!
