Bump Golang version to 1.21 and replace slice utils with stdlib

This bumps the Golang version used to build the module to 1.21. That enables us to make use of the new `slices` package, which implements generic functions over slices. Using those, we can remove the hand-crafted utils and replace them with direct usage of the standard library. Signed-off-by: Markus Thömmes <[email protected]>
