Subject: [PATCH] build: add initial cmake build system

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_add_application
+#
+# Description: Declares a NuttX application as a static library. The
+# corresponding target will be named apps_<NAME>. The first entry into the
+# source list is assumed to be the one containing main() and will thus receive a
+# -Dmain=app_main definition during build.
+#
+# Usage: nuttx_add_application( NAME <string> [ PRIORITY <string> ] [ STACKSIZE
+# <string> ] [ COMPILE_FLAGS <list> ] [ INCLUDE_DIRECTORIES <list> ] [ DEPENDS
+# <string> ] [ MODULE <string> ] [ SRCS <list> ] )
+#
+# Parameters: NAME          : unique name of application PRIORITY      :
+# priority STACKSIZE     : stack size COMPILE_FLAGS : compile flags SRCS :
+# source files MODULE        : if "m", build module (designed to received
+# CONFIG_<app> value) DEPENDS       : targets which this module depends on
+# NO_MAIN_ALIAS : do not add a main=<app>_main alias(*)
+#
+# (*) This is only really needed in convoluted cases where a single .c file
+# contains differently named <app>_main() entries for different <app>. This
+# situation should really be changed into a separate main file per actual app
+# using a shared user library.
+#
+# Example: nuttx_add_application( NAME test SRCS file.cpp STACKSIZE 1024 DEPENDS
+# nshlib MODULE ${CONFIG_EXAMPLES_TEST} )

+# nuttx_parse_function_args
+#
+# This function simplifies usage of the cmake_parse_arguments module. It is
+# intended to be called by other functions.
+#
+# Usage: nuttx_parse_function_args( FUNC <name> [ OPTIONS <list> ] [ ONE_VALUE
+# <list> ] [ MULTI_VALUE <list> ] REQUIRED <list> ARGN <ARGN>)
+#
+# Input: FUNC    : the name of the calling function OPTIONS   : boolean flags
+# ONE_VALUE : single value variables MULTI_VALUE : multi value variables
+# REQUIRED  : required arguments ARGN    : the function input arguments,
+# typically ${ARGN}
+#
+# Output: The function arguments corresponding to the following are set:
+# ${OPTIONS}, ${ONE_VALUE}, ${MULTI_VALUE}
+#
+# Example: function test() nuttx_parse_function_args( FUNC TEST ONE_VALUE NAME
+# MULTI_VALUE LIST REQUIRED NAME LIST ARGN ${ARGN}) message(STATUS "name:
+# ${NAME}") message(STATUS "list: ${LIST}") endfunction()
+#
+# test(NAME "hello" LIST a b c)
+#
+# OUTPUT: name: hello list: a b c
