testwm2: Fix video modes menu hit detection when highdpi or logical size used (#4936)

Browse Source 
* SDLTest_CommonDrawWindowInfo: log SDL_RenderGetScale, SDL_RenderGetLogicalSize

* testwm2: fix video modes menu hit detection in High DPI cases

- also when logical size is specified, e.g.
  `--logical 640x480 --resizable --allow-highdpi`

* add function to determine logical coordinates of renderer point when given window point

* change since to the targeted milestone

* fix typo

* rename for consistency

* Change logical coordinate type to float, since we can render with floating point precision.

* add function to convert logical to window coordinates

* testwm2: use new SDL_RenderWindowToLogical

* SDL_render.c: alternate SDL_RenderWindowToLogical/SDL_RenderLogicalToWindow
