Anyone who inherits from `GUI::Clipboard::ClipboardClient` will receive
clipboard notifications via `clipboard_content_did_change()`.
Update ClipboardHistoryModel, TextEditor and TerminalWidget to inherit
from this class.
This switches tracking CPU usage to more accurately measure time in
user and kernel land using either the TSC or another time source.
This will also come in handy when implementing a tickless kernel mode.
As threads come and go, we can't simply account for how many time
slices the threads at any given point may have been using. We need to
also account for threads that have since disappeared. This means we
also need to track how many time slices we have expired globally.
However, because this doesn't account for context switches outside of
the system timer tick values may still be under-reported. To solve this
we will need to track more accurate time information on each context
switch.
This also fixes top's cpu usage calculation which was still based on
the number of context switches.
Fixes#6473
The `float => double => float` round trip seen in a couple of places
might pessimize the code. Even if it's truncated to an int in the end,
it's weird not to use the functions with the `f` suffixes when working
with single precision floats.
Since applications using Core::EventLoop no longer need to create a
socket in /tmp/rpc/, and also don't need to listen for incoming
connections on this socket, we can remove a whole bunch of pledges!

This warning informs of float-to-double conversions. The best solution
seems to be to do math *either* in 32-bit *or* in 64-bit, and only to
cross over when absolutely necessary.
