feat: Upgrade gdb-xtensa-esp32-elf to 16.3

[biggerfisch]

Summary

Upgrades gdb-xtensa-esp32-elf to be build from 16.3 source.

This also moves the python compatibility matrix from 3.8-3.11 to 3.10-3.14 and supplies zlib 1.3 compatibility.

The custom wrappers are no longer needed as there are rust binaries build for that purpose in the build process now.

There's a few other misc changes, but they are mostly just to make things build correctly

I reviewed and see no obvious issues, but I'm not going to Approve because I don't have enough context.

thanks @biggerfisch !

did you confirm that these select the correct architecture (based on $1 arg to the rust wrapper i guess)? i think you can do it like this once the conda package is installed (eg to a test environment):

❯ xtensa-esp32s3-elf-gdb --batch --ex 'show environment' | rg XTENSA_GNU_CONFIG
XTENSA_GNU_CONFIG=/home/noah/.espressif/tools/xtensa-esp-elf-gdb/16.2_20250324/xtensa-esp-elf-gdb/lib/xtensa_esp32s3.so

$ xtensa-esp32-elf-gdb --batch --ex 'show environment' | grep 'XTENSA'
XTENSA_GNU_CONFIG=/Users/avery/micromamba/envs/memfault/lib/xtensa_esp32.so

Seems to work!
