[Nexthop][m4062nhp] Add platform mapping CSVs and JSON

[zackary-nexthop]

Pre-submission checklist

• I've ran the linters locally and fixed lint errors related to the files I modified in this PR. You can install the linters by running pip install -r requirements-dev.txt && pre-commit install
• pre-commit run

Summary

Adds the platform mapping input files for m4062nhp: m4062nhp_port_profile_mapping.csv, m4062nhp_static_mapping.csv, m4062nhp_si_settings.csv, and m4062nhp_profile_settings.csv, along with the generated platform_mapping.json.

Test Plan

• Platform Mapping Generation Verification CI regenerates platform_mapping.json from the CSVs and confirms it matches the checked-in file.
• All 128 ports come up with correct GID/lane mapping, tested on an m4062nhp system.

@srikrishnagopu it should be good now, for both PRs. Note that I've overridden the empty CSVs that you've added, and there were a few things e.g. in the headers that didn't match. Seems to be ok by looking at other platforms, but let me know if I should do otherwise.
