Adding dependency analyzer to kpm

Adding dependency analyzer (`dpa`) into kpm will allow us to build minimal KRE and TPA list in the first round of build. This is the first step towards a further reduced build script.

The `kpm adp` will build a manifest file lists the files to be included in KRE from CoreCLR and other nuget packages. It can also build the tpa.cpp includes a minimal TPA list.

Here's an example of the KRE manifest (for CoreCLR x86)
```

Will it be helpful to put it in a template file in the project?
