Earlier we only had link in PDF a11y on which action could be performed. Now more annotations are to be added in PDF a11y which are actionable. e.g. highlights. This CL renames the variables and functions from link to annotation in action handling pipeline as the same variables and functions will be used for all actionable annotations. Additionally an enum PP_PdfAccessibilityAnnotationType is introduced to disambiguate between the different annotations on which action is to be performed.
