Add option to disable breaking markdown links

[tg-x]

Grav breaks links by removing certain attributes if it finds them.
There should be a global configuration option to turn this off instead of adding &noprocess one by one to each link.

This is an unintuitive anti-feature that breaks user expectations of being able to link to pages without unintended side-effects of breaking links by silently dropping commonly used attributes.
There have been several reports before from users unwittingly stumbling upon this, e.g. #989, #1877

Only a few reports in 5 years, disabling site-wide would mean huge chunks of functionality suddenly not working, leading to more issues/questions/etc. Might be better to put a good entry in the doc's so people find the solution quickly after googling.

This warrants a global option to disable though, as there are many cases where you either need the pass through of query parameters, or media-processing disabled altogether. It would be advantageous to be able to get the media with query-parameters and have Grav process it afterwards.

I ran into the same issue.
