Mostly a revert of commit b1def7145f ("arch: deprecate `_current`").
This commit was part of PR #80716 whose initial purpose was about providing
an architecture specific optimization for _current. The actual deprecation
was sneaked in later on without proper discussion.
The Zephyr core always used _current before and that was fine. It is quite
prevalent as well and the alternative is proving rather verbose.
Furthermore, as a concept, the "current thread" is not something that is
necessarily architecture specific. Therefore the primary abstraction
should not carry the arch_ prefix.
Hence this revert.

Moves the arch_swap() declaration out of kernel_arch_interface.h
and into the various architectures' kernel_arch_func.h. This
permits the arch_swap() to be inlined on ARM, but extern'd on
the other architectures that still implement arch_swap().
Inlining this function on ARM has shown at least a +5% performance
boost according to the thread_metric benchmark on the disco_l475_iot1
board.

CONFIG_ENTROPY_GENERATOR is now enabled by default as soon as
"zephyr,entropy" is set in the device-tree. Since the sub-Kconfig
CONFIG_ENTROPY_NRF5_RNG is also enabled by default on nrf boards,
this means that the driver is pulled in the build and intialized
at boot. This might cause runtime issues during some IRQ/kernel
tests, so it's better to remove "zephyr,entropy" on these tests.

Introduce `CONFIG_RISCV_GP_PURPOSE` choice to make sure that only
one of `CONFIG_RISCV_GP` or `CONFIG_RISCV_CURRENT_VIA_GP` can be
enabled, instead of relying of dependencies.
To do that, introduce a new
`CONFIG_RISCV_SOC_HAS_GP_RELATIVE_ADDRESSING` that can be selected
by SoC when it implemented global pointer (GP) initialization for
relative addressing in its linker.
`CONFIG_RISCV_GP` will be the default choice when

According to the RISC-V Instruction Set Manual: Volume II, Version 20240411
(Section 3.1.6.6), some implementations may choose to track the dirtiness
of the floating-point register state imprecisely by reporting the state to
be dirty even when it has not been modified. This option reflects that.

What is changed?
- Added a new mps3 board an552 for the soc corstone300.
The qualifier to build/run application with board mps3/an552 is
`mps3/corstone300/an552` for secure and
`mps3/corstone300/an552/ns` for non-secure.
- Added FVP variant to enable FVP testing with corstone300
and it uses the ARM FVP `FVP_Corstone_SSE-300_Ethos-U55`.
The qualifier to build/run application with FVP is
`mps3/corstone300/fvp` for secure and
`mps3/corstone300/fvp/ns` for non-secure.
- Note: the qualifier to build/run application with board mps3/an547
is now changed to
`mps3/corstone300/an547` for secure and
`mps3/corstone300/an547/ns` for non-secure.
How is it changed?
- Moved common code from mps3/an547 to corstone300.
- Renamed soc for an547 to corstone300 and added
a new soc corstone300/an552.
Why do we need this change?
- This enables FVP support and testing for corstone300.
- SOC/qualifier for mps3/an547 was renamed to reduce code redundancy
- A separate FVP variant was added for AN552 because, the TFM board
used for non-secure variant differs for FPGA and FVP.
TFM board `arm/mps3/corstone300/fvp` should be used when testing
AN552 with FVP and `arm/mps3/corstone300/an552` should be used when
testing with AN552 FPGA.

We now use hwmv2 to list boards instead of relying on twister specific
config files.
One yaml files (twister.yaml for now) will have all the data needed for
all possible targets and variations of a board reusing most of the data
where possible and variations can override the top level data.
Twister keeps track of 'aliases' of boards and identifies that for
example native_sim is the same as native_sim/native, so either names
will be possible in both test yaml files or on the command line,
however, the reporting will always use the full name, so no there is no
confusion about what is being tested/built.

Apply the following changes to `nrf54h20dk` and `nrf9280pdk`:
* Convert `perm-*` properties to the newly introduced `nordic,access`,
both in board files and tests.
* Redefine shared regions to specify multiple access owners per node,
and ensure that each such region is reserved by one domain at a time.
`cpuapp_cpurad_ram0x_region` is only enabled by Radiocore, while
`cpuapp_cpucell_ram0x_region` is only enabled by Application core.
* Divide `shared_ram3x_region` so that each sub-region is owned by a
different domain. Their addresses must be rounded down to fit the
current UICR format.
