We were marking all literal candidates as addressable so we were
getting invalid candidates like "&int()". Fix it to only mark literal
struct, array, slice and map types as addressable.
I also fixed the unnamed literal candidate to pass the dereferenced
expected type. For example, if the expected type was "*[]int" we were
passing a literal type of "*[]int" which wasn't working anymore. Now
we pass "[]int" and take its address as "&[]int{}".

We have multiple use cases for scanning: goimports, import completion,
and unimported completions. All three need slightly different features,
and the latter have very different performance considerations. Scanning
everything all at once and returning it was not good enough for them.
Instead, design the API as a series of callbacks for each
directory/package: first we discover its existence, then we load its
package name, then we load its exports. At each step the caller can
choose whether to proceed with the package. Import completion can stop
before loading exports, goimports can apply its directory name
heuristics, and in the future we'll be able to stop the scan short once
we've found all the results we want for completions.
I don't intend any significant changes here but there may be some little
ones around the edges.

We now support taking the address of objects to make better completion
candidates. For example:
i := 123
var p *int = <> // now you get a candidate for "&i"
This required that we track addressability better, particularly when
searching for deep candidates. Now each candidate knows if it is
addressable, and the deep search propagates addressability to child
candidates appropriately.
The basic propagation logic is:
- In-scope *types.Var candidates are addressable. This handles your
basic "foo" variable whose address if "&foo".
- Surrounding selector is addressable based on type checker info. This
knows "foo.bar.<>" is addressable but "foo.bar().<>" isn't
- When evaluating deep completions, fields after a function call lose
addressability, but fields after a pointer regain addressability. For
example, "foo.bar()" isn't addressable, but "foo.bar().baz" is
addressable if "bar()" returns a pointer.

This is the start of a significant refactoring to implementations,
references, and rename (i.e. everything that searches across
packages). The main goal of the refactoring is to push the package
variant logic from internal/lsp into internal/source so that all users
of source benefit, not just internal/lsp. It also makes it easier to
write tests for various cases because the source tests invoke the
source package directly (so previously did not include all the package
variants).
Currently source.Identifer() handles lots of disparate use cases.
Things like definition and hover don't care about package variants but
do care about other random bits of info that may not apply to
implementations or references. So, I'm splitting implementations out
from source.Identifier. As I work through references and rename
hopefully things will end up separated into smaller chunks.
I also improved implementation deduping to happen earlier. I thought I
could dedupe using obj.Pos(), but mirror objects in package variants
have different positions (suggesting they aren't reusing the
same *ast.File). Instead I used token.Position to dedupe.
