libsysprof-analyze: add listmodel of embedded files

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.
