NF: Gesture refactor to allow for mappable gestures

[david-allison]

Purpose / Description

#8078 contains a large refactor to our gesture processing which allows arbitrary mapping of key inputs to commands

Currently, we map from Gesture -> Command

And we want to map from Command -> [Gesture] after the linked PR is completed

This brings the code closer to this PR, in a series of non-functional commits

The aim is that this change is fairly trivially reviewable, so we get closer to the idea

EDIT: Ref: #6052 (link is out of order)

How Has This Been Tested?

Unit tested

LGTM - this will be an interesting feature for 2.16 (more general mapping, and support for more peripherals, as this all lands, yes)

Gah, sorry. Missed the androidTest classes, they're not built on a rebuild

All clean and passes this time ⚡
