Common: put the namespace-scope constants in the constant address space - #15825

MSL requires every program-scope variable to live in the constant address space. GPUglobalconstexpr() already spells that out per backend, so the constants that reach device code go through it: the particle masses in PhysicsConstants.h, which arrive via PID.h, and the LHC timing and TPC geometry constants.
