MouseKeys "janitorial" work (#1130)

* Move MouseWrapper class into the `plugin::mousekeys` namespace

This helper class is meant to be internal to MouseKeys, so it would be best to
sequester it from the shared `kaleidoscope::plugin` namespace.

* Remove unnecessary explicit MouseWrapper constructor

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Remove trailing underscore from MouseWrapper class name

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Rename Mousewrapper methods to comply with coding style guide

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Make MouseWrapper warping utility methods private

MouseKeys doesn't call these functions directly, and making them private helps
make the API for MouseWrapper clearer.

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Make MouseWrapper public variables comply with code style guide

Variables should be in `snake_case`.  Since MouseKeys is the only client of
`MouseWrapper`, I don't feel it's necessary to go through a deprecation process
for the sake of this rename.

* Remove unnecessary explicit MouseKeys constructor

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Remove trailing underscore from MouseKeys class name

Because the `MouseKeys_` class is now contained in the `kaleidoscope::plugin`
namespace, but the `MouseKeys` object is in the global namespace, we can safely
drop the trailing underscore from the class name, like most other plugins.

* Add some namespace comments

* Make `MouseWrapper::subpixels_per_pixel` constexpr

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Change MouseKeys variables from `static` to member variables

Signed-off-by: Michael Richters <gedankenexperimenter@gmail.com>

* Change name of MouseWrapper object

Instead of `kaleidoscope::plugin::MouseWrapper`, it is now named like a
variable: `kaleidoscope::plugin::mousekeys::wrapper`.

* Downcase directory name to match namespace
