qdev-properties: add size32 property type
Introduce size32 property type which handles size suffixes (k, m, g)
just like size property, but is uint32_t rather than uint64_t. It's
going to be useful for properties that are byte sizes but are inherently
32bit, like BlkConf.opt_io_size or .discard_granularity (they are
switched to this new property type in a followup commit).
The getter for size32 is left out for a separate patch as its benefit is
less obvious, and it affects test output; for now the regular uint32
getter is used.
