This instead moves to a public API on the document to symbolize now
that we've gotten much of the necessary bits private in loading the
document. This commit ensures that we only do loading via the loader
now (and removes the incorrect use from the tests so they too go
through the loader).
We check for NoSymbolizer in document symbols so that we can skip any
decoding. That keeps various use cases fast where you don't want to
waste time on symbolizing if you don't need to look at symbols.
There is plenty more we can do to batch decode symbols with some more
API changes, but that will come after we have kernel/userland decoding
integrated from this library.
We may still want to get all symbols into a single symbol cache, but
given that we have address ranges associated with them, that may not
be very useful beyond the hashtable to pid-specific cache we have now.
If symbols were shared between processes, that'd make more sense, but
we aren't doing that (albeit strings are shared between symbol
instances to reduce that overhead).
and thereby make a bunch of the exposed API on SysprofDocument private.
Instead we'll push some of that to the loader but for now the tests can
keep doing what their doing using the private API.
The goal here is to not expose a SysprofDocument pointer until the document
has been loaded and symbolized via the loader API. Then we can lookup
symbols directly from the document w/o intermediary objects.
Now that we have a lot of this indexed, it's fast enough to do on the
calling thread.

This also indexes the first position of a file by filename so that we can
skip items in the capture file. Generally, embedded files are a single
frame so that will only be one frame to look at. But even when it is a
few frames, they are generally sequential so this vastly reduces how many
frames we'll need to look at for files.
It can be handy to iterate through the traceables and we already have a
bitset index for that. Use the new bitset index listmodel to provide that
filtered list externally without having to inflate every object in the
underlying listmodel, as GtkFilterListModel would have to do.
This will provide better namespacing for the objects inflated from the
document for various frame types. By creating real objects with real
properties we give ourselves quite a bit of flexibility in the data
filtering language coming forth.
