tdf#105975 Add Set field parsing (docx) in LibreOffice Writer

Introduction
------------

In MSWord, you can create a variable with `SET` field and then
reference it later in a formula. When you save your file as `docx`,
this `SET` field is registered in you file. In its current state,
LibreOffice can't parse the `SET` field in `docx` file.

Context of this fix
-------------------

This fix is entirely located in the `DomainMapper_Impl.cxx` file
because it's where the parsing is done.

How this fix works
------------------

First, we add `SET` support by adding it to the `aFields[]` variable.
Next, to handle the `SET` constant, we add a condition (swith case) in
`DomainMapper_Impl::CloseFieldCommand()` to call `handleFieldSet`.
Finally, `handleFieldSet` works like `handleFieldAsk` with small
differences.

Note
----

I have renamed `lcl_ExctractAskVariableAndHint` to
`lcl_ExctractVariableAndHint` because this function is used for both `ASK` and
`SET` fields.
