Revert "QPushButton: fix support of style sheet rule for text alignment"

Browse Source 
This reverts commit 6269438af9, and adds a test.

This change introduced QTBUG-91735, without fixing QTBUG-86857 correctly. The
code already interprets the textAlignment values from the rule, also if no
icon is set. Adding the same, or some default textAlignment to the text flags
if there is no icon doesn't work.

Fixes: QTBUG-91735
Task-number: QTBUG-86857
Pick-to: 6.1 6.0 5.15
Change-Id: Iee07e63a40e72909275f32e1caa28b33a595f879
