LibraryType doesn't support traits

[miku1958]

Description

I want to control the LibraryType(non/static/dynamic) with traits but it is not possible now

Expected behavior

traits is part of LibraryType condition

.library(
	name: "XXXKit",
	type: .condition { traits in
		if traits.contains("iOSDynamic") {
			.dynamic
		} else {
			.static
		}
	},
	targets: ["XXXKit"]
),

Or traits can be access in Package.swift directly

let traits = PackageDescription.Trait.currents

...



.library(
	name: "XXXKit",
	type: traits.contains("iOSDynamic") ? .dynamic : .static,
	targets: ["XXXKit"]
),

Actual behavior

LibraryType is a enum, no condition support
