Copy FindSharedMimeInfo from ECM

Instead of relying on ECM being installed.

We copy other stuff from ECM so be consistent.

+# ------------------
+#
+# Try to find the shared-mime-info package.
+#
+# This will define the following variables:
+#
+# ``SharedMimeInfo_FOUND``
+#     True if system has the shared-mime-info package
+# ``UPDATE_MIME_DATABASE_EXECUTABLE``
+#     The update-mime-database executable
+#
+# and the following imported targets:
+#
+# ``SharedMimeInfo::UpdateMimeDatabase``
+#     The update-mime-database executable
+#
+# The follow macro is available::
+#
+#   update_xdg_mimetypes(<path>)
+#
+# Updates the XDG mime database at install time (unless the ``$DESTDIR``
+# environment variable is set, in which case it is up to package managers to
+# perform this task).
+#
+# Since pre-1.0.0.
