[Kconfig][libcpu] 增加ARCH_CPU_BIG_ENDIAN (#5547) 
* [cpu] 增加ARCH_CPU_BIG_ENDIAN
- 之前RT_USING_BIG_ENDIAN的命名并不合理，予以替换为ARCH_CPU_BIG_ENDIAN
- 删除一处多余的ARCH_CPU_64BIT
- 整理了libcpu/Kconfig的格式

* [libcpu][Kconfig] Cortex-M4&7 select ARCH_ARM_CORTEX_FPU

jiladahe1997 433e5f8147 [bugfix] libcpu/arm/cortex-m/context_gcc: 修复thumb指令集汇编语法错误 
当使用thumb指令集时，要求汇编语法中的“条件执行”要跟在IT指令后面，否则会编译不通过。
报错如下：Error: thumb conditional instruction should be in IT block -- `moveq r4,#0x01'

虽然可以通过指定"-Wa,-mimplicit-it=thumb"选项来告诉编译器识别隐式的IT指令，但是能在代码里面直接加上IT指令的话更好。

thumb指令集“条件执行”arm官网文档：

使用不同的优化等级会出现不同的效果
当使用-O0 等级时，无法正确得到关闭中断之前的状态

Using different optimization levels will have different effects
When the - o0 level is used, the state before the shutdown interrupt cannot be obtained correctly
