Unify dynamicImports and experimentalDynamicComponent options

[nolanlawson]

Today we have the following options that all mean the same thing:

• dynamicImports in babel-plugin-component
• experimentalDynamicComponent in compiler, rollup-plugin, and ssr-compiler

We should unify this. The feature is hardly experimental at this point, so probably it should be called dynamicImports, which is also a better name for it.
