Since [1], GIO supports generic serialization and deserialization of a
GIcon into a GVariant. This is also implemented by GdkPixbuf and could be
used instead of our homegrown code for it.
This commit adds support to another 'icon' key in the metas dictionary
returned by applications for it. The previous 'gicon' and 'icon-data'
keys are still parsed and supported as before, but are now deprecated.

Document and enforce that a meta ID corresponds to the result ID
that we've passed in. This does not break any existing search providers
as far as I'm aware.

We are going to change the interface, so add a new version of it.
Providers will need to opt-in to the new API.
A summary of the differences compared to the previous API:
- ActivateResult() now also takes the search terms and a timestamp as
parameters
- a new LaunchSearch() method is added
