Q{*String,ByteArray}View::length(): use qsizetype, not int

Looks like these ones have been forgotten in the Qt 5 -> 6 upgrade
to qsizetype. Change them to return qsizetype as well,
and fix the docs. Being entirely inline, non-exported classes, we
should be able to get away with it without affecting binary
compatibility. Moreover, there's no reason for keeping them
deprecated.

Requires some minor adjustments, just like the ones done for
size()'s changes.

[ChangeLog][QtCore][QStringView] The length() function
now returns `qsizetype`, not `int`, for consistency with the
other string and container classes in Qt. Following this
change, it has been un-deprecated.

[ChangeLog][QtCore][QAnyStringView] The length() function
now returns `qsizetype`, not `int`, for consistency with the
other string and container classes in Qt. Following this
change, it has been un-deprecated.

[ChangeLog][QtCore][QUtf8StringView] The length() function
now returns `qsizetype`, not `int`, for consistency with the
other string and container classes in Qt. Following this
change, it has been un-deprecated.

[ChangeLog][QtCore][QByteArrayView] The length() function
now returns `qsizetype`, not `int`, for consistency with the
other string and container classes in Qt. Following this
change, it has been un-deprecated.
