uic: Generate version check macros around newly introduced palette color role

Browse Source 
Change ebd3a13b807c6af2684b42d3912549caf7ef82aa introduced a new
QPaletter::PlaceholderText color role which causes the uic-generated
code not to compile when using Qt Designer embedded in Qt Creator with
older (5.9 LTS) kits. Generate a version check macro to fix this.
