The JSON-RPC 2.0 protocol requires that responses objects
have either a "result" or an "error", but not both.
In Go, this corresponds to a non-nil result interface value or a
non-nil error.
However, the generated wrappers for the LSP protocol were passing
non-nil values for both in case of error, due to passing typed-nil
pointers as (non-nil) interfaces (see
https://go.dev/doc/faq#nil_error).
This change fixes the generator to explicitly pass only one or the
other, and re-runs the generator at the existing commit.

The documentation for jsonrpc2.Replier states that
“[i]f err is set then result will be ignored.”
jsonrpc2_v2 documents no such affordance, and the JSON-RPC 2.0
protocol explicitly requires that the result “MUST NOT exist if there
was an error invoking the method.”
Although CL 388600 already avoids returning values in case of error
(which may also help with escape analysis and/or allocation
efficiency), it seems simplest and least confusing to make the
semantic difference between the jsonrpc2.Handler and
jsonrpc2_v2.Handler explicit in the code.

When using gopls remote, existing go env vars are injected in the
initialize message. Setting GOWORK explicitly will impact cmd/go
invocations, for example "go list" during package load. The reason it
impacts is that gopls manually sets PWD to fix paths returned by cmd/go
if the working directory is inside a symlinked directory.
By only propagate GOWORK when it is explicitly set we will ensure that
the behavior is the same when running with or without remote.

We added the int() type conversion because the returned type param A

can be converted). This is a premature suggestion, though, so fix by
suppressing such type conversions for type parameters.

The argument to f.Fuzz is determined, up to the names of arguments,
by the types of the arguments to f.Add. Inside the function argument
of f.Fuzz, only f.Name and f.Failed are allowed.
(The fset passed to fuzz was for debugging. When the change seems solid
it can be removed.)

If a go.work file is present, we activate the workspace mode regardless
of the experimentalWorkspaceModule setting.
Fixing this also revealed a long-standing bug in traversing parent
directories. Amazingly I have no recollection of this bug being
reported, but it is far more likely to be hit with go.work files, when
users regularly open nested subdirectories.

This CL adds support for generating method stubs for named types
that have type parameters and want to implement an interface.
See internal/lsp/testdata/stub/stub_generic_receiver.go for an example.
Note, this CL does not yet support type params on interface declarations.

Before this change, newWorkspace would fall back to other workspace
types if there was an error parsing go.work files, or one of the
workspace modules did not exist. Instead, in those cases, newWorkspace
now successfully builds a *workspace with an error set.
This respects the user's intent when working with a go.work file so that
gopls can surface a diagnostic with the error.
