WebNN: Define XNNPACK Node for pooling MLOperators

This CL implements DefineXnnNodeForPool2d() method that defines XNNPACK
pooling Nodes for averagePool2d MLOperator by
xnn_define_average_pooling_2d() or
xnn_define_global_average_pooling_2d(), and maxPool2d MLOperator by
xnn_define_max_pooling_2d().

Similar to conv2d, this CL only supports the “nhwc” input layout. The
“nchw” input layout could be supported by inserting transpose operators
later. There is a proposal [1] that suggests simplifying the layout's
support. The implementation will be updated according to the WG’s
consensus.

To consolidate the padding sizes setting and calculation, this CL also
introduces the GetXnnPadding2D() helper that is shared by both XNNPACK
convolution 2d and pooling 2d Nodes.

For unit tests, this CL implements the Pool2dTest of MLGraphXnnpackTest
that tests both kinds of pooling operators, including the global average
pooling variant.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
