Implement rudementary support for `DidChangeWatchedFileNotification` for SwiftPM projects: When a file is added, reload the Swift package to compute build settings for it.
This enables proper semantic functionality added to the project after the LSP server was started.
Resolves SR-15633
This adds support for clangd commands for clients which support
dynamic registration (including VS Code), as well as fixes an
issue which prevented clangd's code actions from working.
Also added a test to ensure the clangd code actions work, as well as regenerated the Linux test main (which was missing some other newly added tests).

- Add LSP types for semantic highlighting
- Limited to clients which support dynamic registration for semantic highlighting
- Requires clangd 11 or later
Using dynamic registration (when supported by the client) allows
us to provide different completion options for ObjC and Swift
files.
We should be able to expand this to other capabilities in the future
(e.g. semantic highlighting, execute command support).
A number of tests were failing with the -Onone lifetime changes.
Regardless of what happens with that change, I'd like to keep our tests
passing with the stricter rules since we also test in release builds.
- Avoid short queries (< 3 characters) since they are slow and noisy. Xcode does the same thing.
- Limit the number of results returned:
- Improves performance for queries which match many symbols
- Currently take the first N results to improve performance for large projects
but once we support cancellation we should take the top N.
With this change, tests pass whether we default to server-side or
client-side filtering. Also duplicate a few interesting tests to run
both ways. A future commit will beef up the test coverage for
server-side filtering specifically.
* Forward definition requests when index lookup fails
If we're unable to look up a definition or declaration via the
index, forward the request to the language service.
This allows clangd to support go to definition or declaration
for symbols defined/declared in the AST.
While fallback arguments are being used (either from the fallback build system or fallback settings from the primary build system), withhold semantic diagnostics from sourcekitd and all diagnostics from clangd. This helps prevent user confusion from spurious errors.
- Also remove the DocumentURI standardization in favor of proper equality + hash checks to work around the %40 --> @ encoding issue seen on CI.
