QJsonDocument/Value: fix integer truncation in fromJson(QByteArray)HEADdev

The old code passed the QByteArray's size() to the
QJsonPrivate::Parser ctor's length argument, which, however, was still
'int', truncating. Making matters worse, the Parser ctor only used the
length to calculate an end iterator.

Fix by passing by QUtf8StringView. This also indicates that the Parser
expects UTF-8 input (and not Latin1, e.g.).

As a drive-by, make the Parser ctor explicit.

[ChangeLog][QtCore][QJsonDocument/QJsonValue] Fixed a bug on 64-bit
platforms where fromJson(QByteArray) could report one of the
Unterminated errors for valid input whose size merely exceeded INT_MAX
(2GiB).

Amends the port of QByteArray to qsizetype (Qt 6.0, didn't check exact
commit).
