Userland: Remove "Inspector" program and related utilities

This program has never lived up to its original idea, and has been
broken for years (property editing, etc). It's also unmaintained and
off-by-default since forever.

At this point, Inspector is more of a maintenance burden than a feature,
so this commit removes it from the system, along with the mechanism in
Core::EventLoop that enables it.

If we decide we want the feature again in the future, it can be
reimplemented better. :^)

 ## Development
 * Supplying `# profile` with a process identifier (PID) of `-1` as root enables systemwide profiling.
-* Make applications inspectable by including `MAKE_INSPECTABLE=1` in their environment. Inspectable processes can be examined with [Inspector](help://man/1/Applications/Inspector) via remote procedure calls (RPCs). For example, to make the Eyes application inspectable, enter the following Shell commands:
