[dotnet] sanitized pinvokes that use string

[stephen-hawley]

sanitized the pinvokes that use string.
Note: I did not address the pinvokes that take callback functions - that will be addressed in a later PR.

NBD, but I think this should work due to method overloading:

Suggested change

	static IntPtr dispatch_queue_create_wrapper (string label, IntPtr attr)
	static IntPtr dispatch_queue_create (string label, IntPtr attr)

[rolfbjarne]

CFStringCreateWithCharacters takes a Unicode string:

Suggested change

	using var valuePtr = new TransientString (value);
	using var valuePtr = new TransientString (value, TransientString.Encoding.Unicode);
