Update mallocMC

[chillenzer]

This PR pulls the latest dev of mallocMC. This is planned as a beta phase before the official 3.0.0 release of mallocMC. This version should already be feature complete. Please start testing and report any bugs.

It was a bit of a hassle to update because we need a recent patch of alpaka. Also, there has been a major update of mallocMC's cmake infrastructure, so that entailed a number of changes in PIConGPU's setup, as well as an interface change: mallocMC's allocator now takes an accelerator tag instead of an accelerator directly.

• Wait for Update alpaka #5279 to be merged and potentially rebase.
