make the slot data constinit

because it takes a surprising amount of time to initialise it
at runtime during startup

(*) have to convert the std::function in SfxType to a
function pointer, because the std::function constructor
is not constinit compatible.

(*) the SfxType0..SfxTypeN types need some reinterpret_cast
to work around the lack of zero-sized trailing arrays in c++

(*) Sadly MSVC does not support taking the address of symbols
in constinit structures, so we cannot make the SfxSlot
array constinit.
