David 1d5f5eb6c8 feat(libSceJson2): implement the InitParameter2 constructors and setSpecialFloatFormatType
Resident Evil 4 (PPSA07411, #2776) and PRAGMATA (PPSA02530, #3043) stop
on the absent export with

  what():  _ZN3sce4Json14InitParameter225setSpecialFloatFormatTypeENS0_22SpecialFloatFormatTypeE not implemented

Deathloop, Minecraft Legends and Cyberpunk import the base-object
constructor InitParameter2::InitParameter2(), InitParameterRtti2::
setAllocatorRtti and InitParameterRtti::InitParameterRtti(AllocParamRtti*,
void*, unsigned long), which were NotImplemented stubs.

InitParameter2 is the 40-byte object of SharpEmu and KytyPS5: the
allocator, its user data, the file buffer size and the 32-bit special
float format type at 0x18. Both constructors zero it, setAllocatorRtti
writes the allocation parameters and user data where setAllocator writes
the allocator, and setSpecialFloatFormatType stores the type.
InitParameterRtti's constructor writes its three arguments to the first
24 bytes. The NID WVZBP4IyM+E recomputes from the mangled name and is in
the aerolib database. The enum's values are unknown, so no value is
rejected; the inferred layouts are recorded in TechnicalDebt.
