libsysprof: add instrument to record scheduler switching
...
This is to allow us to look at what processes were running when as a way
to get a high-level overview of usage.

libsysprof: sort frames with timsort
...
These are largely pre-sorted, but not fully when you have merged data. This
uses timsort to speed that up a bit.
In particular, the comparison of various sorts break down to (for a
~32,000,000 record capture.
g_array_sort_with_data() => 3.9 seconds
qsort_r() = > 3.7 seconds
gtk_tim_sort() => .79 seconds

libsysprof: setup perf streams in prepare
...
This starts the perf streams from prepare instead of from record so that
we can do the linux instrument work in prepare. The samples are dropped
until our start-time is set.
Doing it this way removes sysprof-cli and sysprofd greatly from the
overhead in the callgraph which is useful so that the user gets to see
what they really care about.
It has the added benefit that we're less likely to see the pkla processes
showing up from authorizing our D-Bus connection for creating per streams.

Otherwise we end up recording ourselves too much. Do it before even though
there is a small race condition chance to miss a process spawning at the
