HTML-AAM: MSAA+IA2 for input types that map to IA2_ROLE_DATE_EDITOR #61

Email from @asurkov:

input type date - it should be similar to type color input, i.e. 'depends on implementation', so that if the control is implemented a text box, then it should have ROLE_SYSTEM_TEXT role. Also expose text-input-type:date when a text box.
....
same for input type date and time
....
el-input-localdateandtime, el-input-input-month and el-input-week are same as date type
