Key remapper is not scaled in opengl output mode in SDL2 version

[evertvorster]

Describe the bug

I use opengl as output for its nice pixel mappings. I also use the SDL 2 version of dosbox-x.
When I hit F12+M to open the keyboard remapper, it is rendered at the native resolution of my screen, and since that is a fairly high resolution screen, it ends up almost unreadably small.

Steps to reproduce the behaviour

Use opengl as output and SDL2 version of dosbox-x
Run dosbox-x
Hit F12+m

Expected behavior

The keyboard remapper to be scaled to be full screen, ideally through the same opengl renderer
