0e6ede8929 kconfig: Rename CONFIG_FLOAT to CONFIG_FPU
This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

c8f7cd5462 kconfig: Make the CPU_HAS_FPU_DOUBLE_PRECISION option global.
This option now applies to the RISC-V architecture and is no longer
a ARM only configuration.

58232d58e0 riscv: Add support for floating point
This change adds full shared floating point support for the RISCV
architecture with minimal impact on threads with floating point
support not enabled.

407b49b35c cmake: use find_package to locate Zephyr
Using find_package to locate Zephyr.

Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.

Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.

It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

aec9a8c4be arch: arm: Move ARM code to AArch32 sub-directory
Before introducing the code for ARM64 (AArch64) we need to relocate the
current ARM code to a new AArch32 sub-directory. For now we can assume
that no code is shared between ARM and ARM64.

There are no functional changes. The code is moved to the new location
and the file paths are fixed to reflect this change.

4f77c2ad53 kernel: rename z_arch_ to arch_
Promote the private z_arch_* namespace, which specifies
the interface between the core kernel and the
architecture code, to a new top-level namespace named
arch_*.

This allows our documentation generation to create
online documentation for this set of interfaces,
and this set of interfaces is worth treating in a
more formal way anyway.

6c4fdc61ef tests: kernel: fp_sharing: increase robustness of float_disable test
This commit make the float_disable test suite more robust
for fast CPUs, by replacing k_sleep(1) with k_yield(), as
the mechanism to trigger thread swap-out during the test
execution. In the wake of using k_yield(), the test, now,
fixes the priorities of all testing threads to 0, making
the test behavior more deterministic with respect to
thread scheduling. The patch doesn't change the functional
behavior of the test.
