Add option TypeName (#62831)

evdev tries to assign the right XI 1.x type-name based on various device
capabilities. In some cases, that fails. e.g. the Mionix Naos 5000 mouse
looks like a keyboard. And we assign a keyboard type in that case since
there are plenty of keyboards that also advertise some axes or others.

Add a new option TypeName to allow for system-wide configuration of such
devices in a quirks file.

This can also be used to address #55867
