Prevent raw Unicode control codes from showing on software keyboard applet. (#3845)
* Revert "Add support for releasing a semaphore to DmaClass (#2926)"

This reverts commit 521a07e612.

* Revert "Revert "Add support for releasing a semaphore to DmaClass (#2926)""

This reverts commit ec8a5fd05362f04cc77436ee3e45a9188777f75e.

* Strip non-visible control codes from strings before they are sent to the software keyboard to prevent ugly unicode blocks from being shown on the UI.

* remove debugging junk

* Initialize stringbuilder capacity at the start to prevent resizing (a tiny tiny microoptimization)

* Update remarks documentation. Remove unneeded imports.

* Removing a test that's actually just redundant
