libsysprof-ui: land new UI design
This comprises a massive rewrite of the UI for browsing captures. We use the SysprofAid class to scan capture files for content and then auto- matically add visualizers and details pages. To avoid breaking things incrementally, we just land this as a very large commit. Not necessarily ideal, but given the amount of stuff that could break, this is easier. As part of this process, we're removing a lot of the surface API so that we can limit how much we need to maintain in terms of ABI.
