Add experimental builder infrastructure for composable_kernel - Add experimental/builder directory with README documentation. - Create initial test infrastructure with CMakeLists.txt and placeholder test. - Update root CMakeLists.txt to support CK_EXPERIMENTAL_BUILDER option. - Update .gitignore to not treat `experimental/builder` as a CMake build directory. This establishes the directory structure for a high-level builder pattern that will provide a semantically-clear interface for constructing CK operations, with initial focus on convolution kernels for MIOpen integration.

Builder
This directory contains the experimental builder feature for composable_kernel.
- Status: In development (October - November 2025)
Overview
The builder provides a high-level, semantically-clear interface for constructing composable kernel operations, with an initial focus on convolution kernels for MIOpen. It leverages modern C++20 features (such as POD structs as non-type template parameters, concepts, and designated initializers) to simplify kernel instantiation and improve developer experience.
This project is a prototype for a more general builder pattern for all of composable_kernel (CK) and CKTile, but is currently limited to formalizing the interface between MIOpen and CK.

CMake Configuration
To enable the experimental builder, configure your build with:
cmake -DCK_EXPERIMENTAL_BUILDER=ON -DCMAKE_CXX_STANDARD=20 ...
Building and testing
During development, build and test from the CK build directory with
ninja test_conv_builder && bin/test_conv_builder
