[Build] Cross-compile for Android on Windows error

[notaJiminLee]

Describe the issue

When attempting to build ONNX Runtime for the Android platform with QNN EP enabled using the shared library build option, the following error occurs. Although the documentation (https://onnxruntime.ai/docs/build/eps.html#qnn) provides an example build command for QNN EP in a shared library configuration, the actual build process produces the error message "Only support Android + QNN builds with QNN EP built as a static library." This raises the question of whether there is an internal requirement for QNN EP to be built as a static library or if there is a discrepancy between the documentation and the build scripts.
