Allow enabling curlDiagnostics

[alexdunae]

NativeCloudSqlite has a curlDiagnostics flag that would be nice to be able toggle.

There is currently an option to increase the log level of CloudSqlite based on the Logger configuration. Could that also be used to enable curlDiagnostics?

itwinjs-core/core/backend/src/CloudSqlite.ts

Lines 966 to 975 in d7bd858

	private static makeCache(args: CreateCloudCacheArg): CloudCache {
	const cacheName = args.cacheName;
	const rootDir = args.cacheDir ?? join(IModelHost.profileDir, "CloudCaches", cacheName);
	IModelJsFs.recursiveMkDirSync(rootDir);
	const cache = new NativeLibrary.nativeLib.CloudCache({ rootDir, name: cacheName, cacheSize: args.cacheSize ?? "10G" });
	if (Logger.getLevel("CloudSqlite") === LogLevel.Trace) {
	cache.setLogMask(CloudSqlite.LoggingMask.All);
	}
	this.cloudCaches.set(cacheName, cache);
	return cache;

Why?

This would be helpful in diagnosing connection issues in applications, notably SSL and proxy configurations.
