Subject: qdoc: Fix handling of default values for function parameters

When using an \fn command to document a function that has default
values for parameter(s), The Clang parser retrieves a relevant
section of the source file that contains the expression for the
default value. In case of \fn, the source is a temporary translation
unit that was constructed on the fly - but it may not exist anymore,
and the default value is lost.

Fix this by storing the contents of the temporary TU for later access.

Fixes: QTBUG-83472
