internal/lsp: add completions of unimported std lib pkgs Unimported packages may be suggested as completion items. Since these are not yet imported, they should be ranked lower than other candidates. They also require an additional import statement to be valid, which is provided as an AdditionalTextEdit. Adding this import does not use astutil.AddNamedImport, to avoid editing the current ast and work even if there are errors. Additionally, it can be hard to determine what changes need to be made to the source document from the ast, as astutil.AddNamedImport includes a merging pass. Instead, the completion item simply adds another import declaration.

internal/imports: sort import candidates by "relevance" When proposing packages to import, we can propose more relevant packages first. Introduce that concept to the pkg struct, and sort by it when returning candidates. In all cases we prefer stdlib packages first. Then, in module mode, we prefer packages that are in the module's dependencies over those that aren't. We could go further and prefer direct deps over indirect too, but I didn't have the code for that handy. I also changed the alphabetical sort from import path to package name, because that's what the user sees first in the UI.

internal/imports: return non-stdlib candidates from GetAllCandidates Scan most sources, including GOPATH, the module cache, the main module, and replace targets as appropriate. Use the cached stdlib instead of scanning GOROOT. We heavily cache the contents of the module cache, so performance is decent. But we have to look at all the modules not in the module cache too to get the right versions of modules (see (*ModuleResolver).canonicalize), which currently isn't cached at all, even just for a single run. That ends up being pretty expensive. The implementation changes are relatively small; add package name loading to scan(), cache that result, and allow callers to control what directories are scanned so that it can skip GOROOT. I also cleared out most of the stdlib from the unimported completion test and added a simple external completion to it for safety's sake.

internal/lsp/source: propose exports for unimported packages When a user completes rand.<>, propose rand.Seed (from math/rand) and rand.Prime (from crypto/rand), etc. Because we don't necessarily have type checking information for unimported packages, I had to add shortcut cases to a number of functions around the completion code. Better suggestions welcome.
