Add UsePagedSqlQuery setting to NucacheSettings

[Zeegaan]

Fixes #13525

Notes

• Implements a UsePagedSqlQuery in NuCacheSettings, that can now be set to false, to instead use Fetch
• Would love to use an IOptionsMonitor instead to track changes, but we cannot refactor this to be non-breaking (even with ActivatorUtilitiesConstructor), as the constructors will be ambiguous 😢

How to test

• Set the UsePagedSqlQuery to false:

  "Umbraco": {
    "CMS": {
      "NuCache": {
        "UsePagedSqlQuery" : false      },

• Assert that you can still create doc types & content, and it works as expected
• Go to the settings -> Profiling dashboard
• Assert that you can rebuild the memory cache.

You can even test the times by cherry picking this Profiling PR in: #13841
and testing with the setting both set to false & true

Looks good to me.. We will need to backport this to v8
