Kacper Sawicki 695de6e0c0 chore(coderd/database): optimize AuditLogs queries (#18600)
Closes #17689

This PR optimizes the audit logs query performance by extracting the
count operation into a separate query and replacing the OR-based
workspace_builds with conditional joins.

## Query changes
* Extracted count query to separate one
* Replaced single `workspace_builds` join with OR conditions with
separate conditional joins
* Added conditional joins
* `wb_build` for workspace_build audit logs (which is a direct lookup)
    * `wb_workspace` for workspace create audit logs (via workspace)
