2d699cd5da LibWeb: Add port blacklist for ResourceLoader::load 
`ResourceLoader::load` now rejects URLs which specify a `port`
associated with network services known to be vulnerable to
inter-protocol exploitation.

Fixes #1735

 		Kernel: Store previous thread state upon all transitions to Stopped (#1753) 
We now store the previous thread state in m_stop_state for all
transitions to the Stopped state via Thread::set_state.

Fixes #1752 whereupon resuming a thread that was stopped with SIGTSTP,
the previous state of the thread is not remembered correctly, resulting
in m_stop_state == State::Invalid and the associated assertion fails.

8aab8faf30 ProfileViewer: Open /boot/kernel for disassembly if possible 
If you have access to /boot/kernel, you can see the disassembly of
kernel code in ProfileViewer. This is really useful! :^)

827e375297 LibELF: Validate the mapped file in DynamicLoader constructor 
ELF::DynamicLoader now validates the ELF header and the program headers
in its constructor. The requested program interpreter from the
PT_INTERP program header is now avaiable via a getter. The dynamic
loader program will want to check that this matches its name, for extra
shenanigans checking.

61acca223f LibELF: Move validation methods to their own file 
These validate_elf_* methods really had no business being static
methods of ELF::Image. Now that the ELF namespace exists, it makes
sense to just move them to be free functions in the namespace.

8dd96ad143 ProfileViewer: Color code the instruction rows by sample percentage

a4006e19d7 ProfileViewer: Don't skip the innermost frame when loading profiles 
We were skipping the innermost frame as a workaround for the kernel
putting garbage data there. Now that the kernel puts the instruction
poiner there, we can load the frame normally! :^)

54fc972a72 MenuApplets: Support memory usage and custom colors in ResourceGraph 
The ResourceGraph menu applet now supports a few command line options:

--cpu / -C to display a CPU usage graph
--memory / -M to display a memory usage graph
--name / -n to set a name which is used to order applets
--color / -c to set the graph color (supports anything
Gfx::Color::from_string() understands)

The SystemServer.ini and WindowServer.ini config files have been updated
to spawn and show two ResourceGraph menu applets, one for CPU usage
(green) and one for memory usage (cyan) - this matches the colors in the
SystemMonitor graphs.
