InputMapper refactor: Modify InputMapper constructor for configuration

We are refactoring Input-mapper(s) to ensure they are configured at the
time of initialisation.

In this CL we are changing InputMapper's constructor to accept the
reader configuration to facilitate initialisation.

Test: build, inputflinger_tests, presubmit checks
