Instead of tagging events with their type, instead we infer the type from
the label pattern.
The standard event creators all have a matching test that returns true
if the the labels pattern matches the ones that would be built by the
creator.
Spans and logs already have a unique label pattern, other event types
required a special label marker.
This makes the system much more extensible, and also cleans up some
the API.

This was the last piece of Event that was public, and it was only public to
allow mutation in tests.
Adding CloneEvent allows tests to create an updated copy rather than
update the event in place.

Also moves core.Key to label.Key, but leaves the implementations
behind for now.
After using for a while, the word Tag conveys slightly the wrong
concept, tagging implies the entire set of information, label maps
better to a single named piece of information.
A label is just a named key/value pair, it is not really tied to the
event package, separating it makes it much easier to understand the
public symbols of the event and core packages, and allows us to also
move the key implementations somewhere else, which otherwise dominate
the API.

Now it only uses the telemetry messages directly rather than the metric system.
This is much faster and more direct, and removes a blocker on improving the
metrics support.
Also fixes the fact that recieced and sent were the wrong way round before,
probably as an artifact of the old protocol logging code, and also removes
the bytes histogram which was a lie (it was a histogram of write sizes that
was presented as a histogram of message sizes)

This separates the concerns of tag collections that have to be iterated
and tag collections that need lookup by key.
Also make it so that events just carry a plain slice of tags.
We pass a TagMap down through the exporters and allow it to be
extended on the way.
We no longer need the event.Query method (or the event type)
We now exclusivley use Key as the identity, and no longer have a
common core implementation but just implement it directly in each
type.
This removes some confusion that was causing the same key through
different paths to end up with a different identity.

This changes the way keys work, there is still a single internal key
implementation for performance reasons, but the public interface is a set of key
implementations that have type safe Of and Get methods.
This also hides the implemenation of Tag so that we can modify the storage form
and find a more efficient storage if needed.

1. logging at debug/rpc.go:105 was corrupting logs.
2. DocumentSymbol (a Server method) now returns []interface{}.
3. The latest version of the LSP changed CompletionItem.TextEdit to
possibly be of the new type InsertReplaceEdit, so the generated Go
code now has TextEdit an interface{} rather than a *TextEdit. This
required a change to tests/util.go.
4. The latest version also introduced several other new types,
and new members in some structs.
Tests pass and the I've use the new gopls a little.

Instead we only have a single exporter, and it must delegate behaviour
to any other exporters it wants to include.
This removes a whole collection of suprises caused by init functions adding
new exporters to a list, as well as generally making things faster, at the small
expense of needing to implement a custom exporter if you want to combine the
features of a few other exporters.
This is essentially the opposite of https://go-review.googlesource.com/c/tools/+/212243
which will now be abandoned in favor of this approach.
