Completion could be slow due to calls to astutil.PathEnclosingInterval
for every candidate during formatting. There were two reasons we
called PEI:
1. To properly render type alias names, we must refer to the AST
because the alias name is not available in the typed world.
Previously we would call PEI to find the *type.Var's
corresponding *ast.Field, but now we have a PosToField cache that
lets us jump straight from the types.Object's token.Pos to the
corresponding *ast.Field.
2. To display an object's documentation we must refer to the AST. We
need the object's declaring node and any containing ast.Decl. We
now maintain a special PosToDecl cache so we can avoid the PEI call
in this case as well.
We can't use a single cache for both because the *ast.Field's position
is present in both caches (but points to different nodes). The caches
are memoized to defer generation until they are needed and to save
work creating them if the *ast.Files haven't changed.
These changes speed up completing the fields of
github.com/aws/aws-sdk-go/service/ec2 from 18.5s to 45ms on my laptop.

Add a symbolStyle configuration option, and use it to parameterize the
following behavior when computing workspace symbols:
+ package (default): include package name in the workspace symbol.
+ full: fully qualify the symbol by import path
+ dynamic: use as the symbol the shortest suffix of the full path that
contains the match.
To implement this, expose package name in the source.Package interface.
To be consistent with other handling in the cache package, define a new
cache.packageName named string type, to avoid confusion with packageID
or packagePath (if confusing those two identifiers was a problem, surely
it is a potential problem for package name as well).

This change will skip ast.CompositeLits if the type can't be found, and
