Refactor: Move Keyboard layout related logic out of IMS
This is precursor to adding new APIs for PK layout selection implementation which will be handled in KeyboardLayoutManager. Bug: 259530132 Test: atest KeyboardLayoutChangeTest Change-Id: I99e396816838c05f28ce57ac50680a3369221921 Change-Id: I4f8ba5350e6affa9f6b2df31262c8aadafc0da05
