Also switch to automatic one by default, as it saves a lot of flash. The manual training
code is left in for now to be able to use it as an option if there are problems with automatic one

The implementation of up_perf_*() is in a different static library in nuttx:
Hardware: libarch.a
Software: libdrivers.a (weak function)
Since functions with weak attributes cannot be correctly replaced in multiple static libraries,
this PR will use macros to replace whether the arch supports hardware perf events

If -fstack-protector-all is enabled, gcc linker will need GCC
SSP(Stack Smashing Protector) support, Since the implement of SSP
is related to the OS, most of embedded toolchain does not provide
ssp support, so an error will be reported when linking:
enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES
arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory
arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory
https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985
Since nuttx has already implemented SSP related hook functions,
so in this PR, we filter out this option in the link phase to ensure that
the implementation of lssp/lssp_nonshared will not be referenced

Reading the CSD field misses 3 bytes as the residual bytes
are not carried over properly. Fix this by adding the missing

The allowed values are
0 Data or unified cache.

"One CCSIDR is implemented for each cache that can be accessed by the processor. CSSELR selects which Cache Size ID Register is accessible, see c0, Cache Size Selection Register (CSSELR)."

In the current implementation of other architectures, it is not really implemented to preserve the context, so it is emulated from other architectures to clear the context.
If this behavior is not implemented, it will cause the xtensa architecture processor to loop assert in the active assert case

1. as we can use fork to implement vfork, so we rename the vfork to
fork, and use the fork method as the base to implement vfork method
2. create the vfork function as a libc function based on fork
function

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

This small fix ensures all DMA pointers are correctly reseted during
DMA setup (when the driver is opened). Without this there could be rare
occurrence of driver pointer to incorrect (invalidate) DMA buffer and thus
saving incorrect characters to upper layer.

Circular buffer does not use DMA linked list therefore function
sam_freelinklist() cannot be called as it would fail on assertion (csa
not defined). Peripheral that calls DMA should care of buffer invalidation
instead.

RISC-V ISA updates
Compared to previous releases, starting from 12.x, the compiler implements the new RISC-V ISA, which introduces an incompatibility issue, and builds might throw error messages like unrecognized opcode csrr.
The reason is that csr read/write (csrr*/csrw*) instructions and fence.i instruction were separated from the I extension, becoming two standalone extensions: Zicsr and Zifencei.
The solution is to add _zicsr and/or _zifencei to the -march option, e.g. -march=rv32imac becomes -march=rv32imac_zicsr_zifencei.
