Apply the same protection to QString, which we know uses the same

A simple 16k file can produce deep enough recursion in Qt to cause stack
overflow. So prevent that.
I tested 4096 recursions just fine on my Linux system (8 MB stack), but
decided 1024 was sufficient, as this code will also be run on embedded
systems that could have smaller stacks.
[ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at
most 1024 nested maps, arrays, and tags to prevent stack overflows. This
should be sufficient for most uses of CBOR. An API to limit further or
to relax the limit will be provided in 5.15. Meanwhile, if decoding more
is required, QCborStreamReader can be used (note that each level of map
and array allocates memory).

Reading of Cbor streams is substantially more complicated than writing
as it requires float16 support. When writing Cbor, we can just choose to
always write 32bit floats, even if we could compress the numbers into
16 bits.
We need Cbor writing in the bootstrap library, but we cannot easily add
float16 support.
Furthermore, Cbor reading is required for plugin support, but not Cbor
writing. It might make sense for some users to build a custom Qt with
Cbor writing disabled.
Therefore, provide two features, cborstreamreader and cborstreamwriter,
split up the code in cborstream.{h|cpp} into several files, and enable
Cbor writing in the bootstrap library.
