4d9ae51c24 internal/lsp: remove source.FileContent
On FileHandle Read now just returns the data hash and error
This makes it more obvious that you should handle the error, rather than hiding
it all in a struct.
We also change the way we get and return content, the main source.File
constructs now hold a FileHandle that then updates on invalidation

2c3de6a5ae internal/lsp: change file system to allow lazy reads
We split aquiring a "handle" from reading a files contents so that we can do the
former eagerly and the latter lazily.
We also "version" the handles so that the same file at different versions is a
different handle.

b012c19798 internal/lsp: trim ASTs for which we do not require function bodies
This change trims the function bodies from the ASTs of files belonging to
dependency packages. In these cases, we do not necessarily need full
file ASTs, so it's not necessary to store the function bodies in memory.

This change will reduce memory usage. However, it will also slow down
the case of a user opening a file in a dependency package, as we will
have to re-typecheck the file to get the full AST. Hopefully, this
increase in latency will not be significant, as we will only need to
re-typecheck a single package (all the dependencies should be cached).

d88f79806b internal/lsp: fix swallowed package errors
If a package has an error that makes it completely unparseable, such as containing a .go file with no "package" statement, the error was previously unreported. Such errors would manifest as other errors.

Fixes golang/go#31712

f217c98fae internal/lsp: fix completion insertion
The insertion range for completion items was not right. The range's
end was 1 before the start. Fix by taking into account the length of
the prefix when generating the range start and end.

Now instead of a "prefix", we track the completion's
"surrounding". This is basically the start and end of the abutting
identifier along with the cursor position. When we insert the
completion text, we overwrite the entire identifier, not just the
prefix. This fixes postfix completion like completing "foo.<>Bar" to
"foo.BarBaz".

bffc5affc6 internal/lsp: support definitions and hover for builtins
This change adds support for definitions and hover for builtin types and
functions. It also includes some small (non-logic) changes to the import
spec definition function.

Additionally, there are some resulting changes in diagnostics to ignore
the builtin file but also use it for definitions (Ian, you were right
with your comment on my earlier review...).

Fixes golang/go#31696

b9584148ef internal/lsp: add structured layers to the cache
This is primarily to separate the levels because they have different cache
lifetimes and sharability.
This will allow us to share results between views and even between servers.

abbb706b23 internal/lsp: enable enhanced hover by default
This change removes the explicit configuration for improved
documentation on hover. We use a comment's synopsis rather than the full
comment.

However, we also add a "noDocsOnHover" setting that is used by the cmd
tests. Ultimately, no one should use this setting and we should remove
it. We leave it temporarily because the cmd tests still need work.

e5f21acdc3 internal/lsp: handle more expected type cases
Calculate expected type in the following cases:

- switch case statements
- index expressions (e.g. []int{}[<>] or map[string]int{}[<>])
- slice expressions (e.g. []int{}[1:<>])
- channel send statements
- channel receive expression

We now also prefer type names in type switch clauses and type asserts.
