We have no tasks running on Cirrus any more. This eliminates the "Build

reference, which was unused.

@CaseyHillers has filed a bug to add a Cocoon endpoint to replace it:

The test was flaky before due to overflowing GPU memory during the test.
The memory leak was fixed here
flutter/engine#49214

Fixes #137669

As a side effect of the fix, this test also runs much faster, from about
3 minutes on my Macbook down to about 25 seconds.

Reverts #139717
Initiated by: LongCatIsLooong
This change reverts the following previous change:
Original Description:
Fixes #131435, #104594, #43400
Needs flutter/engine#48774 (to fix the web test failure).

Currently the method we use for text span hit testing `TextPainter.getPositionForOffset` always returns the closest `TextPosition`, even when the given offset is far away from the text. 

The new TextPaintes method tells you the layout bounds (`width =  letterspacing / 2 + x_advance + letterspacing / 2`, `height = font ascent + font descent`) of a character, the PR changes the hit testing implementation such that a TextSpan is only considered hit if the point-down event landed in one of it's character's layout bounds.

Potential issues:

1. In theory since the text is baseline aligned, we should use the max ascent and max descent of each character to calculate the height of the text span's hit-test region, in case some characters in the span have to fall back to a different font, but that will be slower and it typically doesn't make a huge difference. 

This is a breaking change. It also introduces a new finder and a new method `WidgetTester.tapOnText`: `await tester.tapOnText('string to match')` for ease of migration.

Following https://developer.android.com/build/migrate-to-kotlin-dsl
1/n Add parentheses to method calls 

Should be a no-op change. If you see a behavioral change please flag it.

Extracted from #139717 as-is. Landing this change first so we can avoid doing a g3fix.
