feat: Allow all users to customize reports of type Report Builder

[sagarvora]

Resolves #15074
Continuation of #15494

This PR allows a report of type Report Builder to be created / edited / deleted by any user. This is accomplished without changing permissions for the Report DocType, since this PR only allows non-standard reports of type Report Builder to be saved. They can then be edited / deleted by owner or someone else with requisite permissions.

Delete button in Report View:

Docs to be added after preliminary review. Until then: no-docs

@sagarvora another issue I observed (although not replicated every time) was that sometimes it takes a lot of time for the newly created report to reflect in the report selector dropdown.
