async: remove tag_invoke calls

P2300R9 removed usage of tag_invoke. stdexec still has it
but in order to be forward compliant with the C++26 standard
we should modernize the code and remove its usage. This also
has the benefit of simplifying most sender/receiver implementations.

add support for timed fdio

For certain operations such as reading and writing to a fd for request
response flows, the fd needs to have a timeout to avoid everlasting

timeout.

watchdog: add support for systemd watchdog

Add interfaces and handling for systemd watchdog petting.

Systemd service files can specify a watchdog timeout and systemd will
expect the application to periodically poke a software watchdog, or
else the service will be restarted. This is enabled with the
'WatchdogSec=' service file directive. Add primitives for
interacting with the watchdog APIs.

Enable automatic support in the `async::context` for this watchdog
handling, such that if the watchdog is required (by checking
sd_watchdog_enabled) the daemon will automatically pet at the
appropriate rate, assuming that the `async::context` is functioning
correctly.
