We had the code to calculate the length, but were improperly using it
only for the offset, not the length of the string or its containing
array. That resulted in the generated moc output containing:
QT_MOC_LITERAL(111, 5), // "\xffz"
QT_MOC_LITERAL(114, 5), // "\0012"
QT_MOC_LITERAL(117, 23), // "slotWithAReallyLongName"
The two strings are described as occupying 5 bytes (length 4 + null
terminator), which is incorrect. The offset was correct: 114 - 111 = 3
and 117 - 114 = 3. The new output is:
QT_MOC_LITERAL(111, 2), // "\xffz"
QT_MOC_LITERAL(114, 2), // "\0012"
QT_MOC_LITERAL(117, 23), // "slotWithAReallyLongName"
The effect of the array size calculation would only be felt if moc
decided it needed a second string array (for strings over 65535 bytes),
which would cause the offsets in the second array to be all wrong. There
was no such test until now.

This adds support for additional codecs to QStringConverter when ICU is
available.
We store the converter in the state (d[0]), and its canonical name in
d[1]. We need the name there, as in the clear function we close the
UConverter, and set the pointer to null. Consequently, the actual
conversion functions might need to re-open the converter again. The
advantage of this approach is that clear is used in the destructor of
State, and with this approach we properly clean up the state.
There is however a disadvantage: The clear function was so far also used
for resetting the state when QStringConverter::resetState . Discarding
the whole Uconverter for that is however rather costly. For that reason
we modify resetState to call a new function, State::reset. For existing
converters, it behaves the same as clear; for the ICU based converter,
we call the more efficient ucnv_reset. Code compiled against Qt 6.4 can
benefit from this more efficient version; code compiled against older Qt
versions will continue to work, as the conversion functions can just
recretate the converter from the name.
We can distinguish between ICU and non-ICU converters by checking if the
UsesIcu flag is set.
QStringConverter::name is changed to return the name stored in d[1]. The
interface of the ICU converter has a dummy name, so code using the old
name function from QT < 6.4 still returns something, namely a message
asking the user to recompile.
The function is moved out of line, as we need to check for the private
ICU feature, and want to avoid having that check in the public header.
As the QStringConverter ctor taking a name now can allocate memory, it
can no longer be noexcept. Removing the noexceptness is safe, as it was
only added after Qt 6.3.
Note that we cannot extend the API consuming or returning Encoding, as
we use Encoding values to index into an array of converter interfaces in
inline API.
Further API to support getting an ICU converter for HTML will be added
in a future commit.
Currently, the code depending on ICU is enabled at compile time if ICU
is found. However, in the future it could be moved into a plugin to
avoid a hard dependency on ICU in Core.

supports more text codecs if Qt is compiled with ICU support.
