The way LoKiMC.MC decorates some MC related classes interferes with ROOT
pythonizations producing the error:

Using strings instead of type wrappers for template arguments seems to fix the problem.

Changes needed for LCG 106 (backward compatible with LCG 105)

See merge request !4979

Remove test of GaudiAlg already existing because it has been removed from Gaudi

See merge request !4983

Replace `unsigned long long` with `std::uint64_t` to avoid an error from cppyy,
and replace `unsigned int` with `std::uint32_t` for consistency.

Latest ROOT does not allow implicit conversion from bool to float,
so we have to make it explicit.
