Need mechanism to turn off "middle click paste" for trackpad.

[cascmptrski]

(1) Issue/Bug Description: When using a trackpad to move the cursor and click it is far too easy to find yourself in the wrong area of the trackpad when clicking to move the cursor in a document or to select a section of text. When this happens it either replaces the selection with whatever is on the clipboard or inserts the contents of the clipboard into the document. I have used gnome-tweaks to turn off middle-click paste, but this only works for gtk documents. It would help a lot to be able to select a 2-button only option for a trackpad and leave the three buttons for a real mouse where the user has some control over where they are clicking. This is a critical issue when attempting to use Pop! OS for code development.

As currently implemented developing code or editing documents using a trackpad is unworkable. My only workaround in a wireless mouse.

(2) Steps to reproduce (if you know): Within any document that is being edited start a sequence of cut-move-paste actions and within about 4 or 5 movements you will end up accidentally either replacing desired content or pasting unwanted content in the wrong place. As a point of fact it occurred while attempting to create this report.

(3) Expected behavior: A means to disable (for all applications) the center-button-paste option for a trackpad
