vmagent: support per remoteWrite queues configuration

[AndrewChubatiuk]

fixes #2138

---

Summary by cubic

Adds per-target remote write queues in VMAgent, with fallback to global remoteWriteSettings.queues. This lets each remote write URL use its own queue count.

• New Features
  • Added queues to VMAgentRemoteWriteSpec; CRD schema, API docs, and changelog updated.
  • Controller emits -remoteWrite.queues aligned with -remoteWrite.url: if any per-target value is set, outputs a comma-separated list (missing entries use the global value); otherwise emits a single global flag.

^{Written for commit e151d01. Summary will update on new commits.}

P1: `hasAnyQueuesSet` is set too broadly, which can drop `-remoteWrite.queues` entirely when explicit per-URL values equal the global queue value.</violation>
