Fix testActionNextAndPreviousAtGranularityLineOverTextExtend FAILS

Target CTS test case :
 android.accessibilityservice.cts.AccessibilityTextTraversalTest
   -- testActionNextAndPreviousAtGranularityLineOverTextExtend

1. Modify layout_width, layout_height, textSize in resource file.
In the case of LDPI devices, dip value will be calculated by *0.75px. (1px = 0.75dpi)
For example, 10dip will be 7.5px and ".5" is not accurate value to display on device.
So, I modify the textSize to 12dip(9px) and in similar propotion, layout_width and layout_height change to 96dip(72px).

2. Change the index in Test Code.
Due to above changes, the other test cases using same resource(R.id.edit) will be fail on the other resolution's devices.
So, I set the index values in following test cases to test properly on the other devices.

 android.accessibilityservice.cts.AccessibilityTextTraversalTest
   -- testActionNextAndPreviousAtGranularityPageOverText
   -- testActionNextAndPreviousAtGranularityPageOverTextExtend
