feat: add a driver to manage the compile and link jobs

[mouliangyu]

1. the ptoas.cpp does not provide main anymore. only provides the compile/optimize stage
2. the main is provided by driver.cpp, it works like:

// +----------------------------------------------------------+
// |                        .pto                              |
// +----------------------------------------------------------+
// +-------------+ +------------+ +------------+ +------------+
// | EmitC job   | | VPTO job   | | EmitC      | | VPTO       |
// |             | |            | | child job  | | child job  |
// |             | |            | +------------+ +------------+
// |             | |            | +---------------------------+
// |             | |            | | Fatobj link job           |
// +-------------+ +------------+ +---------------------------+
// +-------------+ +------------------------------------------+
// | C++ source  | |                fatobj                    |
// +-------------+ +------------------------------------------+

这里emit的是logicalName, CCE会把对 device kernel 的调用解析成 _mix_aic/_mix_aiv 引用，导致链接时找不到符号
