evas: Fix text effect which has shadow direction

Summary:
If text object has outline and shadow effect (OUTLINE_SHADOW or OUTLINE_SOFT_SHADOW), and has shadow direction except BOTTOM_RIGHT then outline is not displayed.
So fix logic of style checking.

OUTLINE_SOFT_SHADOW effect of text object is different with text block, so fix it.

Test Plan: Make text obect with OUTLINE_SHADOW or OUTLINE_SOFT_SHADOW effect with any direction except BOTTOM_RIGHT
