When we create popup annotations, we also create the dictionary
associated with it. For regular annotations, the dictionary
associated with an annotation is not owned by annotation,
and will be released separately. But our created dictionary is not
associated with any other data structure, it would be leaked if not
released by the associated annotation.
Add a boolean to indicate the ownership to the dictionary, and release
the owned dictionary during the destruction of an annotation.

Comparing CFX_ByteString for annotation subtypes is inefficient and
error-prone. This CL uses enum class to compare annotation subtypes.
Also, remove unused IPDFSDK_AnnotHandler::GetType() and
FSDK_XFAWIDGET_TYPENAME.

Each annotation has its contents, and users should be able to see the
contents. In this patch, PDFium creates a Popup annotation for each
annotation and stores the author and the content. When a user mouse
hover on the annotation, PDFium draws the corresponding Popup annotation
and displays the content.
Also, roll DEPS for testing/corpus to 5867fa6.

CPDFSDK_Annot::GetType should be renamed to GetAnnotSubtype as it returns
annotation subtype. Also, CPDFSDK_Annot::GetSubType is only used to check if
the annotation is signature widget. Thus, change the method to
IsSignatureWidget. Lastly, rename CPDF_Annot::GetSubType to
CPDF_Annot::GetSubtype to match with spec.

Avoid using reference argument and return CFX_FloatRect instead.

Now that Document::getAnnot works and annotation instances
can have its properties changed, consider the following
scenario:
- A PDF content has an annotation without AP and
CPVT_GenerateAP is called to generate one.
- However the annotation also has its hidden flag set (/F 2),
and CPVT_GenerateAP bails out earlier, not generating an AP.
- When the PDF's Javascript runs, it acquires an instance of
this annotation object, bounded to JS using Document::getAnnot(),
and set its "hidden" flag to false.
- At this point, the annotation should get drawn, but it does
not because its "AP" was never generated.
CL fixes this scenario by making PDFium able to lazy
generate APs, if needed.

Now that PDFium supports drawing of more annotation
types, it should also respect the "hidden" flag that
annotations might feature.
For instance, in IE/Acroread if an annotation is flagged as
"hidden" it does not get drawn.
CL adds a check for the specific "hidden" flag, not drawing
annotation that are flagged with it, in order to match IE + acrobat
reader behavior.
The "flags" definition can be seen by looking at "/F {value}"
syntax in a PDF file source, where {value} is an predefined
integer value.
Test: PDF files being added in [1].

This CL splits the header file apart. The cpp files are not touched as part
of this CL, they will be done as a followup. This de-duplicates the fpdf_doc.h
