Stefan Kalkowski c3d4802ac8 hw: re-implement lazy FPU context switch
The new implementation of the FPU and FPU context is taken out to
separate architecture-dependent header files. The generic Cpu_lazy_state
is deleted. There is no hint about the existence of something like an
FPU in the generic non-architexture-dependent code anymore. Instead the
architecture-dependent CPU context of a thread is extended by an FPU
context where supported.

Moreover, the current FPU implementations are enhanced so that threads
that get deleted now release the FPU when still obtaining it.

Fix #1855
