Allow getting asset library and active asset handle via context

`CTX_wm_asset_library()` returns the active asset library from the workspace,
or the the Asset Browser one while inside that. The active asset handle is set
by the Asset Browser and the asset view UI template so that operators executed
via the template can access it.
