f25123df66 LibCore: Remove main event loop
The main event loop functionality was used in just two places where the
alternative is a bit simpler. Remove it in favor of referencing the
event loop directly, or just invoking `EventLoop::current()`.

Note that we don't need locking in the constructor since we're now only
modifying a thread-local `Vector`. We also don't need locking in the
old call sites to `::with_main_locked()` since we already lock the
event loop in the subsequent `::post_event()` invocation.

7af87e8e6b SystemMonitor: Move process window to GML
Extra stuff done in this commit to facilitate the above (if you want to
really push my commit count, ask for more atomicisation):
- Register a bunch of widgets that are used in the process window.
- Allow setting the pid after the fact for the process state widget.

160bda7228 Applications: Use default constructors/destructors
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#cother-other-default-operation-rules

"The compiler is more likely to get the default semantics right and
you cannot implement these functions better than the compiler."

69c1910037 LibCore: Allow EventLoops to run on multiple threads safely
The event loop system was previously very singletony to the point that
there's only a single event loop stack per process and only one event
loop (the topmost) can run at a time. This commit simply makes the event
loop stack and related structures thread-local so that each thread has
an isolated event loop system.

Some things are kept at a global level and synchronized with the new
MutexProtected: The main event loop needs to still be obtainable from
anywhere, as it closes down the application when it exits. The ID
allocator is global as IDs should not be shared even between threads.
And for the inspector server connection, the same as for the main loop
holds.

Note that currently, the wake pipe is only created by the main thread,
so notifications don't work on other threads.

This removes the temporary mutex fix for notifiers, introduced in
0631d3fed5 .

d2024f04bd Userland: Cast unused BackgroundAction::construct() results to void
User code does not need to keep this alive, so casting to void is safe.
But maybe a bit weird.

356d5821e7 SystemMonitor: Request symbolication wihout source positions
The Stack tab doesn't display this information anyway, so there's no
need to have it calculated and returned to us.

Using a table display this information in a much more organised and
flexible way than than what can be achieved with a TextEditor.

840822b8f1 LibSymbolication+SystemMonitor: Show ELF object in stack
This small patch allows SystemMonitor's Stack tab to show the name of
the ELF object to which the displayed address refers to. This gives a
bit more of contextual information to the viewer.

A better to show this is probably a table, but I'm not that familiar yet
with the GUI framework in general, so I'm keeping things simple.

e11d177618 Userland+LibGUI: Add shorthand versions of the Margins constructor
This allows for typing [8] instead of [8, 8, 8, 8] to specify the same
margin on all edges, for example. The constructors follow CSS' style of
specifying margins. The added constructors are:

- Margins(int all): Sets the same margin on all edges.
- Margins(int vertical, int horizontal): Sets the first argument to top
  and bottom margins, and the second argument to left and right margins.
- Margins(int top, int vertical, int bottom): Sets the first argument to
  the top margin, the second argument to the left and right margins,
  and the third argument to the bottom margin.

ee3a73ddbb AK: Rename downcast<T> => verify_cast<T>
This makes it much clearer what this cast actually does: it will
VERIFY that the thing we're casting is a T (using is<T>()).

Use a Threading::BackgroundAction to symbolicate stacks. This avoids
blocking the main thread and keeps the GUI running (mostly.)

252cb54310 LibSymbolication+SystemMonitor+bt: Move symbolication back in-process
Process-separated symbolication was cute, but ultimately the threat
model is kinda silly. We're already *running* the binary, but we're
afraid to parse its symbol table? :^)

This commit makes SystemMonitor and bt do symbolication in-process.
SymbolServer and the symbol user will be removed separately.
