增加find_MDK_EXEC_PATH、find_IAR_EXEC_PATH函数 (#180)

* 增加find_MDK_EXEC_PATH、find_IAR_EXEC_PATH函数

* correct comment

* 增加初始化检查IAR\MDK路径是否设置
如果设置，将路径赋给RTT_EXEC_PATH环境变量

通过上述两个函数可以直接获取到 #178 新增的Kconfig CONFIG_SYS_CREATE_IAR_EXEC_PATH

勾选自动更新IAR、Keil工程时，可以自动根据Kconfig设置的CONFIG_SYS_CREATE_IAR_EXEC_PATH自动更新IAR 和Keil工程。仅限于自动更新时，自动设置IAR所在路径，使用手动scons --target=iar时，依然走rtconfig.py下的IAR路径。
