Previously only qstr*icmp() were tested and the test data was sent via
QString and {en,de}coding. Use a local data-type to package pointers
to actual string literals for passing to these functions that take
them. Fold the various tests involving null pointers and empty
strings into the general testing, removing from "singularity" tests,
and combine the remainders of those tests into a single test of
singular cases for QByteArray::ompare. Move all these tests to
alongside the existing tests for QByteArray::compare. Use nullptr
rather than 0 as the null string.

Previously it handled Latin-1, which made it incompatible with UTF-8,
which is now our preferred 8-bit encoding. For Qt6 it is limited to
ASCII. Adjusted tests to match. QLatin1String::compare() turned out
to be relying on qstrnicmp()'s Latin-1 handling.
Removed some spurious Q_UNLIKELY()s and tidied up code a little in the
process.
[ChangeLog][QtCore][Important Behavior Changes] Encoding-dependent
features of QByteArrray are now limited to ASCII, where previously
they worked for the whole of Latin-1. This affects case-insensitive
comparison, notably including qstricmp() and qstrnicmp(), and
case-transforming functions.

resize() to a smaller size does not reallocate in Qt 5 if the container
is not shared. Match this here.
As a drive-by also fix resize calls on raw data strings to ensure
they are null terminated after the resize.

It has been the case for both QStringLiteral and QByteArrayLiteral
since Qt 5.0, and Q_ARRAY_LITERAL since Qt 6.0.
Since it's definitely surprising, add a note in the docs, which
is "somehow" consistent with the interpretation of capacity as
the biggest possible size before we reallocate. Since it's 0,
any manipulation of the size will cause a reallocation.
(Alternatively: the capacity() is for how many elements memory was
requested from the free store. No memory was allocated, so 0...)

We already detach immediately since change
c2d2757bcc. That basically removes
the main purpose of having QChar/ByteRef, and we can just as well
get rid of those classes for Qt 6.

The Mutable flag now contains the information on whether the data this
QArrayData points to is mutable. This decouples the mutability /
immutability setting from the allocation and from the type of data,
opening the way for mutable raw or foreign data.
There are still plenty of places in the source code that check the
size of the allocation when it actually wants d->isMutable(). Fixing
this will require reviewing all the code, so is left for later.
The needsDetach() function is moved to QArrayData and
de-constified. It returns true when a reallocation is necessary if the
data is to be modified.

QByteArray::fromBase64 was liberal in its input, simply skipping
over invalid characters. As a side-effect of this, it had
no error reporting, meaning it could not be used to convert
fromBase64 _and_ validate the input in one go.
Add more option flags to make fromBase64 strictly validate
its input. Since we want to know whether it has succeeded
or not, and the existing fromBase64 overloads do not
allow for that, introduce a new function that returns
an optional-like datatype.
While at it: base64 decoding can be done in-place; add an
rvalue overload to enable this use case.
[ChangeLog][QtCore][QByteArray] Added the new fromBase64Encoding
function.
