* remove verilating devices (use ventus-gpgpu/sim-verilator)
* do not use ENV to find spike/rtlsim/cyclesim any more. Find the libs from ${VENTUS_INSTALL_PREFIX}, find spike header files from ${SPIKE_SRC_DIR}. Need to pass these cmake variables from cmake config cli interface
* add INSTALL_RPATH ($ORIGIN)
* For not-implemented-yet functions of ventus.h, add a empty implement (return 0)
it will select real simulation backend depending on ENV{VENTUS_BACKEND}
for examle:
VENTUS_BACKEND=spike ./matadd
VENTUS_BACKEND=rtlsim ./matadd
VENTUS_BACKEND=cyclesim ./matadd
symbolic link to spike or auto_select
auto_select driver: support VENTUS_BACKEND=XXX more backend name alias cyclesim driver: add more logs
and passing it to simulation device
简单描述driver功能与支持的环境变量 配合修改源码符合文档，相比于旧有支持的环境变量更加容易让用户理解
对于b+tree这样的有多个ELF的测例，第一次upload ELF中的.text段所在地址后没有内存释放，导致第二个ELF无法获取到指定的地址 解决：第二次upload ELF时前释放第一次ELF的内存
TODO: 部分VT_CAPS_*尚未支持，后续添加
