feat(compiler-sfc): analyze script bindings

[CyberAP]

Should it support injections and computeds as well?
Which cases should be supported in addition to the basic ones?
I also think that having multiple parsing passes for <script> blocks is not optimal, maybe babel's ast should be contained within the SFCScriptBlock?

• BindingMetadata can only be one of 'data' | 'props' | 'setup' | 'options' - so anything that is not data, setup or props goes into options.

• Re attach AST on the block: yeah I think that's a good idea.

I've managed to do parsing only once by passing AST directly to analyzeScriptBindings.
Is this ok? Should analyzeScriptBindings be exported in that case?
