Fix ONNX frontend code generation (#25937)

### Details

ONNX frontend has code generation when `BUILD_SHARED_LIBS=OFF` which
targets a file inside source directory.
When configuring the project, the generated file is written to the
sources directory.
If two configurations are running at the same time (i.e. when trying to
build the package with `vcpkg` it configures debug and release builds
concurrently), both `cmake` instances append lines to the same file
inside source directory which leads to corrupted file content and
cryptic build errors.

This change makes the script write generated header file to a directory
inside build directory, so that two different configuration processes
don't interfere with each other.
