feat: support bundle updates to enable pprof and telemetry collection (#21486)

- Adds pprof collection support now that we have the listeners
automatically starting (requires Coder server 2.28.0+, includes a
version check). Collects heap, allocs, profile (30s), block, mutex,
goroutine, threadcreate, trace (30s), cmdline, symbol. Performs capture
for 30 seconds and emits a log line stating as such. Enable capture by
supplying the `--pprof` flag or `CODER_SUPPORT_BUNDLE_PPROF` env var.
Collection of pprof data from both coderd and the Coder agent occurs.
- Adds collection of Prometheus metrics, also requires 2.28.0+
- Adds the ability to include a template in the bundle independently of
supplying the details of a running workspace by supplying the
`--template` flag or `CODER_SUPPORT_BUNDLE_TEMPLATE` env var
- Captures a list of workspaces the user has access to. Defaults to a
max of 10, configurable via `--workspaces-total-cap` /
`CODER_SUPPORT_BUNDLE_WORKSPACES_TOTAL_CAP`
- Collects additional stats from the coderd deployment (aggregated
workspace/session metrics), as well as entitlements via license and
dismissed health checks.
