The signal fastpath aims to optimize the seL4_Signal operation. In this commit, it is implemented for MCS AARCH64 (SMP and non-SMP). The fastpath does not include the case where signaling results in a higher priority thread being unblocked and made available for scheduling (on any core). It does not fastpath the case where the signaled thread is donated a scheduling context and has its FPU state saved in the FPU of a core.
