Vlad Lazar 36b875388f pageserver: replace the locked tenant config with arcsawps (#7292) ...

## Problem
For reasons unrelated to this PR, I would like to make use of the tenant
conf in the `InMemoryLayer`. Previously, this was not possible without
copying and manually updating the copy to keep it in sync with updates.

## Summary of Changes:
Replace the `Arc<RwLock<AttachedTenantConf>>` with
`Arc<ArcSwap<AttachedTenantConf>>` (how many `Arc(s)` can one fit in a
type?). The most interesting part of this change is the updating of the
tenant config (`set_new_tenant_config` and
`set_new_location_config`). In theory, these two may race, although the
storage controller should prevent this via the tenant exclusive op lock.
Particular care has been taken to not "lose" a location config update by
using the read-copy-update approach when updating only the config.
