Do not recreate navigation bar for screen layout change
According to the document, the screenLayout can be changed
if orientation is changed:
If you want to manually handle orientation changes in your
app you must declare the "orientation", "screenSize", and
"screenLayout" values in the android:configChanges attributes.
The activity configuration follows the behavior for years, so
[1] makes the calculation of display screen layout (sent to
application) consistent, instead of computing a smallest value.
NavigationBar was configured to recreate if it detects a screen
layout change, then it may trigger an additional display config
change since [2] considers the insets of decor windows as a
factor to affect screen size.
The InterestingConfigChanges flags of NavigationBar was just
reused from [3] which is not added for NavigationBar. So a
simple redraw is enough for screen layout change, that is also
more efficient.

Bug: 233855302
Test: Simulate screen layout change (LONG) of rotation
adb shell wm size 720x1280
adb shell wm density 320
atest ConfigChangeTests#testRotation90NoRelaunch
Test: Simulate large screen change (width>600dp)
The navigation bar shows correctly with
adb shell wm size 2600x2200
Switch navigation mode / rotate device.
adb shell wm size reset
