## Description
This PR ensures that activity-based deadline extensions ("activity
bumping") are not applied to prebuilt workspaces. Prebuilds are managed
by the reconciliation loop and must not have `deadline` or
`max_deadline` values set or extended, as they are not part of the
regular lifecycle executor path.
## Changes
- Update `ActivityBumpWorkspace` SQL query to discard prebuilt
workspaces
- Update application layer to avoid calling activity bump logic on
prebuilt workspaces

Marked as a breaking change as the previous activity bump was always the TTL duration of the workspace/template.
This change is more cost conservative, only bumping by 1 hour for workspace activity. To accommodate wrap around, eg bumping a workspace into the next autostart, the deadline is bumped by the TTL if the workspace crosses the autostart threshold.
This is a niche case that is likely caused by an idle terminal making a workspace survive through a night. The next morning, the workspace will get activity bumped the default TTL on the autostart, being similar to as if the workspace was autostarted again.
In practice, a good way to avoid this is to set a max_deadline of <24hrs to avoid wrap around entirely.
The refactored ActivityBump query did not take into account the
template-level TTL, resulting in potentially incorrect bump
amounts for workspaces that have both a user-defined and template-
defined TTL that differ.
This change is ported over from PR#10035 to reduce the overall
size of that PR.
Also includes a drive-by unit test in autobuild for checking template autostop/TTL.

- Adds dbtestutil.WithTimezone(tz) to allow setting the timezone for a test database.
- Modifies our test database setup code to pick a consistently weird timezone for the database.
- Adds the facility randtz.Name() to pick a random timezone which is consistent across subtests (via sync.Once).
- Adds a linter rule to warn against setting the test database timezone to UTC.
* Adds unit-style tests for activityBumpWorkspace
* Ports logic of activityBumpWorkspace to a SQL query
* Updates activityBumpWorkspace to call above query
