Increased font size for messages

Motivation and context

On phones with a rather large screen, the given font sizing is
small even for the default theme. Increasing the size helps with
readability and reduces strain on the eyes.

Should fix #5160.

Got here from the release notes of the latest element release. This looks horrible on my Galaxy Z Fold 3 on both the inner and cover screens. The text looks like I went into my system settings and bumped my DPI up a notch, not at all consistent with other apps.

Please offer a size slider or something, the size looks terrible on my phone, I've always wanted to customize it.

I also think this should be reverted, element should just use the system default.
