Wire DERPTLSConfig through the CLI, SDK, tailnet, VPN client, agent, and
health checks to allow custom TLS configuration for DERP connections.
The main use case is to be able to set a custom CA and also present
client certs (mTLS). See https://github.com/coder/tailscale/pull/105 for
related changes.
Adds three new global CLI flags:
- `--client-tls-ca-file` / `CODER_CLIENT_TLS_CA_FILE`
- `--client-tls-cert-file` / `CODER_CLIENT_TLS_CERT_FILE`
- `--client-tls-key-file` / `CODER_CLIENT_TLS_KEY_FILE`
Based on community PR #22695 by @ibdafna, with autogeneration issues
fixed (protobuf version mismatches in .pb.go files, golden file
regeneration, lint fixes).

<summary>Relationship to #22695</summary>
This is a clean reimplementation of the changes from #22695 on top of
current `main`, with the following differences:
- **Removed**: Accidental protobuf version changes in `.pb.go` files
(contributor had `protoc v6.33.4` vs project's `protoc v4.23.4`)
- **Added**: Properly regenerated golden files and docs via `make gen`
- **Fixed**: Lint issue (`var-declaration` revive warning on explicit
type in `createHTTPClient`)
- All meaningful code changes are identical to the original PR
</details>
- Adds `testutil.GoleakOptions` and consolidates existing options to
this location
- Pre-emptively adds required ignore for this Dependabot PR to pass CI
https://github.com/coder/coder/pull/16066
This cleans up `root.go` a bit, adds tests for middleware HTTP transport
functions, and removes two HTTP requests we always always performed previously
when executing *any* client command.
It should improve CLI performance (especially for users with higher latency).
I also noticed we don't have `goleak` enabled for CLI tests, this commit
adds it, but commented out. The reason being that we're nowhere near
being able to enable it yet.
