Kernel: Make sys$perf_register_string() generate the string ID's

Browse source 
Making userspace provide a global string ID was silly, and made the API
extremely difficult to use correctly in a global profiling context.

Instead, simply make the kernel do the string ID allocation for us.
This also allows us to convert the string storage to a Vector in the
kernel (and an array in the JSON profile data.)
