This forwards the internal clipboard to the host, but does not handle the primary selection nor accessing the host's clipboard internally. The source is recreated for every new copy, rather than being reused when it is still valid. This doesn't seem to be necessary, but doing it differently leads to clipboard managers not becoming aware of the reused copies (under Sway, `wl-paste --watch` doesn't notice them), which at least suggests that not reusing is more common.
This is an extension of the previous commit, also forwarding the primary selection to the host. This does not add support for accessing the host's primary selection internally.

This forwards the internal clipboard and primary selection to the host. However,
this does not yet add support for accessing the host's clipboard/selection
internally.
The source for both the clipboard and primary selection are recreated every
time, rather than being reused when they are still valid. Although this doesn't
seem to be necessary, it does appear to be the norm. In particular, the only
difference in behavior I could notice between the two methods is that clipboard
managers are not aware of the new copy when it is reused (this is at least the
case with
wl-paste --watchunder Sway).
