[8.19](backport #51804) chore: import autodiscover repository

[mergify]

Imports the code from elastic-agent-autodiscover repository (back) into beats repository.

This imports all commits done in the elastic-agent-autodiscover repository since extracting it from Beats repository back in 2022. The cutoff commit is elastic/elastic-agent-autodiscover@8187a88. I rewrote the commits to have the [elastic-agent-autodiscover] prefix.

The linter flagged some violations in Beats files that only had import paths changed. I fixed those that were fixable automatically with --fix parameter of golangci-lint and added nolint directives on the other violations to minimize the scope of changes.
