Add new APIs to get marked content id

FPDF_StructElement_GetMarkedContentID() provides access to the MCID
in a struct element. It assumes /K in a struct element dictionary
is a number. This may be a case sometimes, but /K can also be an
array with mixed types. See ISO 32000-1:2008, section 14.7.6 for
example. Adding FPDF_StructElement_GetMarkedContentIdCount() and
FPDF_StructElement_GetMarkedContentIdAtIndex() to address this
issue.

This change supersedes FPDF_StructElement_GetMarkedContentID(). It
provides a mechanism to access MCID at an index while supporting
the case where struct element dictionary is a number. After this
change, FPDF_StructElement_GetMarkedContentID() becomes redundant
and should be deprecated.
