This change adds user settings for enabling inlay hints, modeled roughly after analyzers. This will allow users to turn on specific inlay hints that they like and leave others off. With all of the inlay hints turned off by default, we can now enable inlay hints.

Testing
LSP has "marker tests" defined in internal/lsp/testdata, as well as
traditional tests.
Marker tests
Marker tests have a standard input file, like
internal/lsp/testdata/foo/bar.go, and some may have a corresponding golden
file, like internal/lsp/testdata/foo/bar.go.golden. The former is the "input"
and the latter is the expected output.
Each input file contains annotations like
//@suggestedfix("}", "refactor.rewrite"). These annotations are interpreted by
test runners to perform certain actions. The expected output after those actions
is encoded in the golden file.
When tests are run, each annotation results in a new subtest, which is encoded in the golden file with a heading like,
-- suggestedfix_bar_11_21 --
// expected contents go here
-- suggestedfix_bar_13_20 --
// expected contents go here
The format of these headings vary: they are defined by the
Golden
function for each annotation. In the case above, the format is: annotation
name, file name, annotation line location, annotation character location.
So, if internal/lsp/testdata/foo/bar.go has three suggestedfix annotations,
the golden file should have three headers with suggestedfix_bar_xx_yy
headings.
To see a list of all available annotations, see the exported "expectations" in tests.go.
To run marker tests,
cd /path/to/tools
# The marker tests are located in "internal/lsp", "internal/lsp/cmd, and
# "internal/lsp/source".
go test ./internal/lsp/...
There are quite a lot of marker tests, so to run one individually, pass the test path and heading into a -run argument:
cd /path/to/tools
go test ./internal/lsp/... -v -run TestLSP/Modules/SuggestedFix/bar_11_21
Resetting marker tests
Sometimes, a change is made to lsp that requires a change to multiple golden files. When this happens, you can run,
cd /path/to/tools
./internal/lsp/reset_golden.sh
