[Keyboard] Modernize KMAC (#6131)

* [Keyboard] Modernize the KMAC implementation

This brings the matrix implementation more in line with the current
default matrix code.
It also simplifies the implementation quite a bit.

* [Keyboard] Add layout support to KMAC

+# Keymap for the winkey version of KMAC
+
+This is the default keymap for the winkey version of the PCB. It implements the same features as the official default KMAC firmware.
+
+## Layers
+
+The keymap have two layers. To access the functions on the second layer, hold down `Fn` and press the corresponding key.
+
+### Layer 1: Default Layer

+## Macros
+
+These are mostly useless and serve more like examples I guess.
