webnn: Support gatherElements in tflite converter

There is no TFLite operator to map directly WebNN gatherElements, but
it can be supported with tfl.gather_nd, the test cases[1] and the
doc[2] show the gather_nd can gether not only slices but also elements,
but gather_nd can't gather along the axis, so the indices used by
gather_nd need to be calculated by unravelling the flat index and
adjusting value with the axis.

The coordinates are calculated by the stride of each dimension. For
example a shape (3, 2) array can map to the following coordinates:
// index row, col
// [[0, 1,] [[0, 0], [0, 1],
// [2, 3,] => [1, 0], [1, 1]
// [4, 5,]] [2, 0], [2, 1]]

Adjusting the coordinates with WebNN indices operand along the axis,
// unravelled index WebNN indices axis = 0 TFLite indices
// [[0, 0], [0, 1], [[1, 0], [[1 ,0], [0, 1],
// [1, 0], [1, 1] [2, 1], => [2, 0], [1, 1],
// [2, 0], [2, 1]] [0, 2]] [0, 0], [2, 1]]

Update READMEs for animation tests

First in a series of patches to document best practices for animation
tests. This patch adds a readme for non-WPT animation tests, and
updates the readme for CSS transitions. Each tip was recently used to
fix a flake / failure introduced with the migration of css transition
tests from using run_web_test.py to run_wpt_test.py.

Refactor touch-handler-count

The original test is using an internals method to access the handler
count. We can make this more universal by adding listeners and
measuring the number of responses. Also my using touch instead of some
other category of events, we are not necessarily fully testing on the
mac, where real devices don't have touch screens.

This patch, uses click instead of touch events since fully handled on
all platforms and moves the test to wpt/dom/events. The tracking of a
nested document's handlers in the parent frame is not to spec, so that
portion of the test was removed.

Refactored to use variants for document/window/element, to determine
the event target. The animationstart event supports bubbling, making
it a suitable candidate for the test.

Refactor pointerevents_iframe-touch-action-none

Problems in the test:

• onload only ensures the parent frame is loaded and not the child
  frame. Fix by explicitly triggering load of the child frame and
  waiting on completion.
• assumes message from child frame will be posted and processed by the
  time the button is pressed, but this can happen too quickly. Fix by
  waiting on a message promise from the child frame.
• concatenation of events from the child frame is needlessly
  convoluted and likely the result of copy-paste from another test.

1 flake over 100 runs without fix.
0 flakes over 600 runs with the fix.
