Fix the same crash as golang/go#66195, this time in Analyze: don't set
invalid Go versions on the types.Config.
The largest part of this change was writing a realistic test, since the
lack of a test for golang/go#66195 caused us to miss this additional
location. It was possible to create a test that worked, by using a flag
to select a go1.21 binary location.
For this test, it was required to move a couple additional integration
test preconditions into integration.Main (otherwise, the test would be
skipped due to the modified environment).

Absent a reproducer this is hard to test, yet the change makes intuitive

Working with go.sum files in integration tests was cumbersome, involving
temporarily modifying the test to call env.DumpGoSum(...), then copying
its output into the static go.sum file.
For some tests, we may actually want to check in a fixed go.sum file,
but the majority of the tests just want to avoid go.sum errors. To
support this use case, add a new RunOption that writes the go.sum file
before starting the test. Use this option in a test to illustrate its
usage.
Also, update DumpGoSum to use the faster "./..." pattern to create the
go.sum output. "..." matches all modules, but we only care about the
main module.

Creating more than this number of goroutines just increases

A set of suggested completions is long if there are more than ten

If a client sends back changes to file, gopls can decide if a
completion was used or not, but it does not try to tell if the client

This CL moves the stdversion analyzer out of gopls,
into the exported analyzer tree, whence it will be
vendored into cmd/vet in a follow-up.

This CL adds a "View package documentation" code action to any
selection in a Go source file. Its command has two effects:
1) to start a web server associated with the current LSP
server, with coupled lifetimes, and register a handler
to serve the package documentation; and
2) to direct the client to open a browser page
showing the package documentation for the selection.
The server is a minimal imitation of pkg.go.dev,
working off the cache.Package representation. This means
we can display doc markup even for unsaved editor buffers,
and show type-derived information such as method sets
of each type.
Clicking through to the source--which on pkg.go.dev goes
to cs.opensource.google--causes the client editor to
navigate directly to the source file, using the magic
of showDocument requests.
The web server is secure in that all its endpoint URLs contain
an unguessable secret, so a local process belonging to
a different user can't access source code by port scanning.
The CL includes a test that
(a) the webserver content reflects edits (even unsaved)
in the source buffers, and
(b) that "clicking" through the source link causes
the server to navigate the client editor to the
correct source location.
A couple of tests that asserted "no code actions" needed
to be tweaked, as now there is always at least one
code action in any Go source file.

The runtime.GOROOT function is about to be marked as deprecated, which
will generate a diagnostic that isn't expected in format.txt test case.
Pick another hopefully somewhat future-proof identifier, since dealing
with this doesn't seem to be in scope of this test case.
For golang/go#51473.

Rename methods on cache.Package to eliminate unnecessary "Get" prefixes.
Also rename pkg.go to package.go.
