RFR: 8341370: Test java/awt/Frame/ShapeNotSetSometimes/ShapeNotSetSometimes.java fails intermittently on macOS-aarch64 [v2]

[Manukumar V S]

> ShapeNotSetSometimes.java fails intermittently with a RuntimeException on macOS-aarch64
> Test threw exception: java.lang.RuntimeException: Test failed. The shape has not been applied.
> 
> Fix:
> The test has been modified to take a screenshot of the area and then analyse the pixel color in the screenshot rather than getting individual pixels from the screen for each test.
> Also the timeout of the test has been increased to 5 minutes(300 seconds) as sometimes it times out with the default timeout of 2 minutes(120 seconds).
> 
> Testing:
> After fixing the test, it has been run 40 times per platform(Windows, Linux, MacOS x64 and MacOS aarch64) using Mach5 and got 100% pass rate .
