[M34-Merge] Not showing IME in URL Box when second tap to url box

[Problem] IME is not shown after changing focus from
edit field on page to browser url bar. After that tapping
on any edit field cause no IME displaying.
[Solution] Removing internal flag (holding information whether
keyboard is visible or not) from im_context_efl and replace it
with ecore_imf_context_input_panel_state_get call.
