For #81574

This applies the fix from #84878 to a number of other descriptor classes in our codebase

For #81574

See #84669 for details of the problem around strict function types. This change converts `SyncActionDescriptor` to use a static `create` function. This allows us to make the `create` function generic so that it can take the correct types for strictFunctionTypes

* Clean up diff

`searchRipgrep.enable` and `search.runInExtensionHost` are no longer
used. A code search for `searchRipgrep` and `runInExtensionHost` shows
no matches.

While they were originally used to determine if searches should be run
with ripgrep, they were later replaced with `search.useRipgrep`. That
setting itself is now deprecated and does the same thing as
`search.usePCRE2` (so it actually doesn't disable ripgrep), but at least
it does something.

So delete these settings that are beyond deprecation - they do nothing.
