Nicolas Pitre f1f63dda17 arm64: FPU context switching support 
This adds FPU sharing support with a lazy context switching algorithm.

Every thread is allowed to use FPU/SIMD registers. In fact, the compiler
may insert FPU reg accesses in anycontext to optimize even non-FP code
unless the -mgeneral-regs-only compiler flag is used, but Zephyr
currently doesn't support such a build.

It is therefore possible to do FP access in IRS as well with this patch
although IRQs are then disabled to prevent nested IRQs in such cases.

Because the thread object grows in size, some tests have to be adjusted.
