[ASTextNode2] Provide compiler flag to enable ASTextNode2 for all usa…

…ges. (TextureGroup#410) * [ASTextNode2] Provide compiler flag to enable ASTextNode2 for all usages. The runtime switch is helpful, but is too slow to be shipped in a large production application where startup time is carefully optimized. Although this doesn't pass text-related snapshot tests when enabled, it does allow apps to rely on built-in components like ASButtonNode using the same text stack as when they are manually creating ASTextNode2 instances. A simpler approach would be to use a #define ASTextNode ASTextNode2, but this would create unusual keyword highlighting in code referencing ASTextNode. However, because it would be less invasive and this is not on by default, we could do that instead if preferred. * Update AsyncDisplayKit.h * [ASTextNode2] Improve naming and documentation of ASTEXTNODE_EXPERIMENT_GLOBAL_ENABLE * [ASTextNode2] CHANGELOG.md for TextureGroup#410.
