BREAKING CHANGES

• We now use flexbox for header elements which could break some existing style code which relied on absolute positioning.
• Now the back button test ID can be customized using headerBackTestID option
• We now require newer versions of safe area context library.
• Previously, the stack header accepted scene and previous scene which contained things such as descriptor, navigation prop, progress etc. The commit simplifies them to pass route, navigation, options and progress directly to the header. Similaryly, the previous argument now contains options, route and progress.
• The header can be hidden with headerShown: false already. Using both headerMode='none' and headerShown together causes confusion. So it's time to drop the unnecessary headerMode prop.
