Mostly automated fixes from running:
```
go run golang.org/x/tools/go/analysis/passes/modernize/cmd/modernize@latest --fix ./...
```
But carefully reviewed, and several fixes reverted as they looked like
they potentially could be less performant, and in a few cases due to
bugs in the analyzer that changed semantics of the code. Will report
these upstream.
Mostly good fixes though!

* v1/plugins: Address race in config access
I ran into this race condition on another PR:
https://github.com/open-policy-agent/opa/actions/runs/16655603110/job/47139789057
I have tried to make all manager.Config access thread-safe by adding new
getters for used values. GetConfig is regrettably based on a JSON
roundtrip deep copy of the config. This us used in tests (fine) but also
in the discovery plugin:
https://github.com/open-policy-agent/opa/blob/2d014a89bbbc307d7204817220146ffae992e838/v1/plugins/discovery/discovery.go#L122
getPluginSet is very tightly coupled to the manager.Config and because
of it's dependencies on status and the other plugins packages, it's hard
to break out.
So, for now, I think this is an improvement and worth getting a second
opinion on before more refactoring.

* v1/config: Use add Clone to config
This makes the use of the manager's config more thread-safe and
consistent without more API changes.

* topdown: Add clone() funcs for config structs
NamedValueCacheConfig.Clone, InterQueryBuiltinValueCacheConfig.Clone and
InterQueryBuiltinCacheConfig.Clone have been added.
All Clone methods return a deep copy of the struct. This is tested for
missed new fields using PopulateAllFields, a generic function that
stuffs structs with values for all fields.

This is a simpler version of util.TypedHashMap where the keys
implement a `.Hash()` method and as such won't need one to be passed
in, and where the values are largely ignored by the map. These maps
are smaller / more performant, but most importantly, they are nicer
to work with.
Perf wise, this saves about 600k+ allocs and 40 MB allocated memory
in `regal lint bundle`:
```
1207614875 ns/op 3293454016 B/op 64802095 allocs/op
1197978125 ns/op 3256960504 B/op 64164871 allocs/op
```
Also:
- Use `strings.Builder` instead of `fmt.Sprintf` in one location
- Remove `ValueMap.Copy` as it was only used in a test
