newwin: lock default titlebar | maybe lock out compact density

A number of chrome elements can cause variance in the remaining height

on all desktop

• lock density to normal
• lock bookmarks toolbar to always on (I know it eats height real estate)
• menu bar should be off on all platforms, we could reset that on app start (personally I would also like to block the Alt key toggling it)

on windows/mac

• lock title bar off

on linux

• lock title bar on

This should help reduce variance in inner window sizes on same resolutions to less buckets. I'm doing some fuzzy what if analysis based on resolutions, system scaling, docker/taskbar size + position, density, bookmarks toolbar, and titlebar ... and OMG the menu bar

This issue is a reminder for me to decide if it's worth it after I do my nested nested nested nested nested nested nested loop analysis - we probably have lots of users in most buckets anyway, so it may not make any difference ... that and @donuts will most likely say no because user choice and usability on lower res machines
