Handle multiple compile commands on client side (needs native server side support)

[yiftahw]

closes #7029

• updates to the c_cpp_properties.json schema and compileCommands setting to accept either a string or array of strings.
• updates to the settings.json schema and default.compileCommands setting to accept either a string or array of strings.
• a single path with non-zero length in c_cpp_properties.json or settings.json is placed inside an array of length 1.
• empty strings are filtered from the array of paths, a single empty string or an empty array are handled as undefined.
• file watcher support for the list of files provided by the user.
• single compile_commands.json is converted to a list of size 1 to consistently send an array (or undefined).
• handle squiggles for errors in c_cpp_properties.json.
• updated C/C++: Edit Configurations (UI) panel to handle multiple compile_commands.json paths.

@bobbrow squiggles are now handled as well. I believe most of the work on the client side is done.
let me know if you have more feedback.

please note there is a new telemetry entry and a new localized string:

message = localize("multiple.paths.should.be.separate.entries", "Multiple paths should be separate entries in an array.");
newSquiggleMetrics.MultiplePathsShouldBeSeparated++;

Thank you very much. Would you also be able to do the changes to the Edit Configurations UI in Extension/ui/settings.* so that multiple paths can be displayed/edited in that view?

looking into it... putting the PR back to draft for now

@yiftahw Your changes/fixes and cpptools updates to allow an array for compileCommands is available in https://github.com/microsoft/vscode-cpptools/releases/tag/v1.23.2

@sean-mcmanus I downloaded the latest pre-release version and copied the binaries to my project folder, and I don't see @Colengms 's added string used
should I copy something else besides cpptools and cpptools-srv ?

[12/6/2024, 8:23:41 AM] "module.cxx" not found in "PLAYGROUND". 'includePath' from c_cpp_properties.json in folder 'undefined' will be used for this file instead.

looks like this string matches file_not_found_in_path instead of file_not_found_in_path2 from #12964
I expected it to look like:

[12/6/2024, 8:23:41 AM] "module.cxx" not found in compile_commands.json files. 'includePath' from c_cpp_properties.json in folder 'PLAYGROUND' will be used for this file instead.

Hi @yiftahw . It looks like these strings' contents got reversed/mismatched. The next insiders should correct that. Otherwise, I believe support for use of an array of strings instead of a single string in the compileCommands field of the configuration object sent to the native side, should now be supported.

@bobbrow Were you going to resolve the comments you made?
