[wrangler] Support jurisdictions for KV namespaces

[oOPa]

KV-2108

Adds jurisdiction support for KV namespaces in two places:

1. wrangler kv namespace create --jurisdiction <us|eu|fedramp> — a hidden flag
   that creates a KV namespace scoped to a specific jurisdiction. Hidden from
   --help because the feature is currently gated to allow-listed accounts
   server-side.

2. An optional jurisdiction field on kv_namespaces bindings in wrangler.jsonc

The tests pass. So I think the SDK did pass the jurisdiction flag to the API correctly.

i don't feel strongly either way, but r2 jurisdiction is a config option too - is that something we should have here too?

[oOPa]

@emily-shen adding it now

@teresalves You might wanna ask the team admin of @cloudflare/workers-kv to add you in the team. I will bypass the check for the CI for now :)
