try_compile: Restore COPY_FILE with CMAKE_TRY_COMPILE_CONFIGURATION

Since commit 0c141b0393 (try_compile: Record output location instead of
reverse computing it, 2022-08-31, v3.25.0-rc1~154^2) we always look for
the "Debug" configuration's output binary from the test project.
Restore looking for the `CMAKE_TRY_COMPILE_CONFIGURATION`.

Fixes: #24180
