Fix reply data can't be decompressed correctly

If the "Accept-Encoding" is not manually specified, it will be
automatically set to the supported encodings by QT and the reply data
will also be automatically decompressed in this case. Setting
"Accept-Encoding" manually will disable the "autodecompress" feature
before QT 6.3.0. Although QT 6.3.x has different behaviors, let QT
specify the "Accept-Encoding" and we will always obtain the decompressed
data.

The macro "QT_NO_COMPRESS" defined when QT is compiled will disable
the zlib support. We can manually address this exceptions.

PR #17438.
