Subject: Typedef'ed layer_state_t to uint32_t (#3637)

* Typedef'ed layer_state_t to uint32_t.

This enables future work with layer_state_t to uint8_t for optimization purposes.

* Removed accidental xeal60 commit

* Revert to egyptian brackets, added sizeof(layer_state_t) so when layer_state_t is redefined it will automagically work.

* Add additional typedefs

* Add checks for setting layer state

* Update tmk_core/common/action_layer.h

Co-Authored-By: alex-ong <the.onga@gmail.com>

* Revert commit.
