Filter LipiInputMethod inputModes by input method hints

Since adding the new component InputModeKey in commit
ea998f43d62ac12fd0f48a51683eb343ee1a52f1 certain tests
(tst_plugin::test_hwrNumericInputSequence) started to fail.

The reason for the failure is the LipiInputMethod which always
returns all the supported input modes (Latin, Numeric and Digits)
regardless of input method hints.

This change modifies this behavior and limits the input modes
to ones actually requested by input method hints.
