*/*: Bump PORTREVISION for known Qt private API abusers

Qt 6.10.1 edition.

These ports are known to directly use or link to a library that uses the
Qt private API and must be rebuilt with every Qt update.

Qt *public* API/ABI compatability is excellent, so most consumers don't
need to necessarily be rebuilt between patch or even minor releases, but
use of the private API breaks this compatibility between even patch
releases and its use is highly discouraged.

This list [1] is based on histortical data. We don't have time to
revisit every port on the list with each Qt update, so if your port has
dropped Qt private headers and was bumped in error, please remove it
yourself if you have write access to the Wiki or alert someone on kde@.

With hat:	kde@

Reported by:	portscout

devel/qxlsx: update the port to version 1.4.7

provide both flavors.

devel/qxlsx: backport one patch from the upstream master branch

It would be required for the upcoming new version of Stellarium,
which constructs QString's from character arrays a lot and having
QT_NO_CAST_FROM_ASCII defined publicly breaks the compilation in
this case.

Discussed with:	Alexander V. Wolf

devel/qxlsx: new port had been added (+)

QXlsx is reader/writer library for Microsoft Excel files (*.xlsx).
Because QtXlsx is no longer supported since 2014, new project had
been created based off of it in 2017.
