Add allow-disallowed-*-in-tests configuration items

[PaulDance]

Description

Dear maintainers,

Whenever using one of the disallowed-* lints, one may only specify what is to be enabled, but very little is provided to conditionally disable. This makes workspace-wide refactors often tedious as one needs to #[allow] or #[expect] each use site of a macro, method, ... in tests (and other non-production modules) when adding a new element to one of these disallowed lists.

In parallel of things like #8477 and #11433, an element that should therefore be both relatively easy and quickly useful to implement would be new configuration items for each of, in order of estimated priority:

• disallowed_methods
• disallowed_macros
• disallowed_types
• disallowed_names
• disallowed_script_idents

to allow one to disable the lint under #[cfg(test)] gates, in a fashion as similar as possible to allow-dbg-in-tests or allow-print-in-tests for instance. The name for each could be allow-disallowed-*-in-tests, for example allow-disallowed-macros-in-tests.

Thanks in advance,
Paul.
