Add experimental JavaScript retrieval APIs.

Add the following set of APIs to retrieve the JavaScript code from
actions in a document's name tree:

- FPDFDoc_GetJavaScriptActionCount()
- FPDFDoc_GetJavaScriptAction()
- FPDFDoc_CloseJavaScriptAction()
- FPDFJavaScriptAction_GetName()
- FPDFJavaScriptAction_GetScript()

This also adds the FPDF_JAVASCRIPT_ACTION type and
ScopedFPDFJavaScriptAction to help manage the lifetime of
FPDF_JAVASCRIPT_ACTION.

This is implemented on top of CPDF_Action, and improves validation in
CPDF_Action to better follow the spec.
