Fix race condition in pointerevent_pointerId_scope

The load event waits for resources such as images and stylesheets to
load, but does not guarantee that child iframes have loaded. This
test was flaking on debug and MSAN builds which are inherently slower
and susceptible to race conditions. This patch addresses the race
condition by deferring loading the iframe until we can trap the signal
that loading is complete, and is a speculative fix for the flake.

Several other tests in this directory also use iframes and may have
the same race condition. Deferring adding a common resource tool
for a frame load promise pending further investigation of these other
tests.

WebCrypto: HDKF and PBKDF2 return an empty ArrayBuffer when length is zero (#49048)

The HKDF and PBKDF2 derive bits operations were changed in [1] to allow
a zero length to be passed and return an empty ArrayBuffer in that case.

This PR updates the tests cases affecting these 2 algorithms in the
cases where zero was passed as the length parameter.

webnn: Support block-wise quantization for DirectML backend

Block-wise quantization divides input tensors into smaller blocks that
are independently quantized, resulting in faster optimization and high
precision quantization 1. It is used for popular language models,
such as phi-3 mini int4 quantized model 2. Related WG issue 3 has
been opened to discussion.

Firstly, this CL validates scale and zero point tensors for block-wise
quantization. Besides, this CL also implements the block-wise
quantization in DirectML backend by using DML_OPERATOR_QUANTIZE and
DML_OPERATOR_DEQUANTIZE which are available in FL >= 6.3.

More validation and conformance tests are added to verify the
implementation.

Nearest neighbor images should not use higher quality

We recently fixed a bug [1] where the discardable image map was not
preserving image quality values. This fix exposed a bug where nearest
neighbor filtering would incorrectly re-use higher-quality images.
Nearest neighbor filtering is used for image-rendering: pixelated and
should not use higher-quality filtering.
