Standard POSIX specification in URL “https://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_timedsend.html” requires that "EBADF" be returned when message queue not opened for writing.So i update the related descriptions in this file, no function changed.

Standard POSIX specification in URL “https://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_send.html” requires that "EBADF" be returned when mqdes is not open for writing. And message priorities range from 0 to {MQ_PRIO_MAX}-1. In this change, i update them to follow POSIX spec.

In POSIX testcase "open_posix_testsuite/conformance/interfaces/mq_receive/11-2.c", it will return "EPERM" when message queue is not opened for reading, but the standard POSIX specification in URL “https://pubs.opengroup.org/onlinepubs/9699919799/functions/mq_receive.html” requires that "EBADF" be returned.So in this change, i update it.

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

NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

It takes about 10 cycles to obtain the task list according to the task
status. In most cases, we know the task status, so we can directly
add the task from the specified task list to reduce time consuming.

There one ways can caused this:
mq_timedreceive
TIMER IRQ do wd_timer -> wd_func1 mq_send
-> wd_func2 nxmq_rcvtimeout -> crash
Resolve:
Stop the watchdog when mq_send

Squashed commit of the following:
Change all calls to mq_send() and mq_timedsend() in the OS to calls to
nxmq_send() and nxmq_timedsend(), making appropriate changes for differences
in return values.
sched/mqueue: Add internal function nxmq_send() and nxmq_timedsend() that are
equivalent to mq_send() and mq_timedsend() except that they do not create
cancellation points and do to not modify the errno variable.
