Make gtk-doc work again

gtk-doc has gained an official CMake module which can fix xrefs.

Meanwhile, our old module has stopped working for whatever reason,
might be that I've botched the LdCategoryView interface somehow.

-# - Finding gtk-doc and building documentation
-# This module provides the following function:
-#
-# GTK_DOC_RUN (
-#   [ALL]
-#   [MODULE <module-name>]
-#   [WORKING_DIR <working-dir>]
-#   SOURCE_DIRS <source-dir> ...
-#   [IGNORE_FILES <file> ...]
-#   [SCANGOBJ <library> [<link-libraries> ...]]
-#   [{SGML | XML} [<mkdb-output-dir> [<mkdb-options>]]
-#   [HTML <html-output-dir> <backend-options>]]
-# )
-#
-# The function creates a target named <module-name>_gtkdocize
-# which will build the documentation as specified by parameters.
-#
-#   ALL          - always build the target
-#   MODULE       - the name of the module
-#                  CMAKE_PROJECT_NAME by default
-#   WORKING_DIR  - path to the working directory
-#                  CMAKE_CURRENT_BINARY_DIR by default
-#   SOURCE_DIRS  - documentation sources
-#   IGNORE_FILES - ignore these files in the process
-#   SCANGOBJ     - build an object hierarchy scanner
-#   SGML         - make SGML output in the spec. directory
-#   XML          - make XML output in the spec. directory
-#   HTML         - make HTML output in the spec. directory
-#                  (requires either SGML or XML)
-#
-# Also creates these virtual symbolic outputs if appropriate:
-#   <module-name>_gtkdocize_scan
-#   <module-name>_gtkdocize_scan_rebuild_types
-#   <module-name>_gtkdocize_scan_rebuild_sections
-#   <module-name>_gtkdocize_scan_gobject
-#   <module-name>_gtkdocize_mkdb
-#   <module-name>_gtkdocize_mkhtml
