Fix incomplete support for built-in jpeg, mng, tiff and gif handlers

Previously, although the configure shell script could configure
built-in support for these image formats, the .pr[io] files
would nevertheless build them as plugins. Support was also
missing from qimagereader and qimagewriter. This has now been
added.

Configure.exe, while clearly intended to support this too,
needed a few minor fixes. For example, the usage of values
"qt" and "yes" was inconsistent.

For both configure tools, the explanation of the *non*-related
options has been clarified, i.e:
    -no-libjpeg
    -qt-libjpeg
    -system-libjpeg
These options have nothing to do with the plugin/built-in
distinction.

There are (still) no configure options for specifying "plugin" or
"built-in" for these image formats. Quite reasonably, "plugin"
is selected for shared Qt and "built-in" is selected for static Qt.
