Add appearance tests for multiple fields month input UI
https://bugs.webkit.org/show_bug.cgi?id=97888

Reviewed by Kent Tamura.

This patch adds tests for multiple fields month input UI and disables
these tests on ports which don't enable both ENABLE_INPUT_TYPE_MONTH
and ENABLE_INPUT_MULTIPLE_FIELDS_UI.

Note: We need to do rebaseline tests to update images for Chromium-Mac
and Chromium-Win.

Note: This patch affects ports which enable both ENABLE_INPUT_TYPE_MONTH
and ENABLE_INPUT_MULTIPLE_FIELDS_UI.
