Explicitly import interfaces from TSCBasic which now allows us to
identify all the swift-tools-support-core interfaces which are in
use in SourceKit-LSP.
This allows sourcekit-lsp to make use of the path remappings recently added to
the index store and IndexStoreDB to remap remote paths into local paths
when loading index data locally.
These remappings can be provided via the `-index-prefix-map` command line flag to sourcekit-lsp or via the `BuildSystem` integration point.
This sets the stage for multi-workspace support. Everything should be handled internally, we are just missing the API to actually open multiple workspaces at this point.

Similar to how we reload the package if Package.swift is changed, we also watch `compilation_database.json` and `compile_flags.txt` and notify the build system delegate that build settings changed if these files are modified.
rdar://92388223 [#486]
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
Remove `settings(for:)` from the BuildSystem API in favor of the change callback
- With the `settings(for:)` method removed, we instead block on a
callback from the `BuildSystemManager` which itself handles
the primary build system callback in conjunction with the fallback
system
- We queue up notifications / requests that reference documents
until we receive the callback.
- Remove language from FileBuildSettings as it is no longer needed,
Swift-specific working dir fixes are now in SwiftCompileCommand
- registerForChangeNotifications should inform its delegate
asynchronously instead of immediately
In preparation for injecting doing more during registration, pass
through the same parameters (add language) so that we can call settings
as necessary.
Find the index store path by searching through the command-line
arguments, and if found, also provide a default database path next to
the index store. Also add command-line arguments so that either of these
can be overridden. We could also easily add these as initialization
options if an LSP client wanted to provide them in the future.
URL can in fact store URIs, it just doesn't have a very nice API to
interact with them. As long as we only operate on absoluteString, we
should be fine though. So instead of implementing the logic for
detecting file URLs ourselves, we can just use a URL as storage for
DocumentURI.
According to the LSP specification, arbitrary URIs can be used as
document identifiers. Instead of internally assuming that all URIs are
URLs, use a DocumentURI enum to represent URIs. These can either be file
URLs or other URIs whose value as treated as an opaque string.
We will be able to split the LSP modules off later. These LSP modules
will provide the ability to write custom LSP servers and clients in
Swift. The sourcekit-lsp repository will build on top of this new
package to provide an LSP implementation that creates a language server
for Swift and C-based-languages.
Introduce a `BuildSystemDelegate` to handle notifications from the build system
* `SourceKitServer` is the main delegate to process these notifications
* Currently limited to changes in `FileBuildSettings`
* Delegate informs the `BuildSystem` of files to watch via `registerChangeWatching(for: URL)` and `unregisterChangeWatching(for: URL)`
* In the future we could have more integration for handling changes in dependencies
Handling changes in `FileBuildSettings`
* `SourceKitServer` sends notifications to the internal LSPs informing them of any opened documents that have changes in their compiler flags
* For clangd, we send a notification to update the compilation database
* For SourceKit/sourcekitd we must close and reopen the file to force a new AST with the new compiler flags
