Ladybird+LibWebView: Add -P/--enable-callgrind-profiling option

Browse source 
This adds a -P option to run Ladybird under callgrind. It starts with
instrumentation disabled. To start capturing a profile (once Ladybird
has launched) run `callgrind_control -i on` and to stop it again run
`callgrind_control -i off`.

P.s. This is pretty much stolen from Andreas (and is based on the patch
everyone [that wants a profile] have been manually applying).
