This commit should fix the concern about uninitialized memory of main
thread that was raised in https://gerrit.zephyrproject.org/r/#/c/12920/
The issue is more general, if it happens that the content of the
CPENABLE flag of any thread is set then any other thread using the CP
may cause a memory corruption.
I'd prefer to avoid the issue by initializing the CP descriptor to 0.
The descriptor itself is few words. We set them to 0 up to CP_ASA, which
is set to a real value.
As the dummy thread instantiated at the kernel startup does not use CP,
there is no CP area in its thread memory buffer. However it is mandatory
that it have the CP descriptor and that cpEnable in that descripot is
set to null. This is ensured by adding XT_CP_DESCR_SIZE to
_K_THREAD_NO_FLOAT_SIZEOF.

fibers/tasks are now just threads and we should not be using
struct *tcs any more.
