tearing: avoid permanent disable due to rejected commits (#2295)

Browse source 
Currently, the cursor plane does not allow async page flips which causes tearing page flips to be rejected if the cursor was moved.

However, in games where no cursor image is present, the async page flips can still work as expected.

Instead of permanently disabling tearing after too many failures, test the output state first before each frame to see if we can commit with tearing_page_flip set to true.
