[mir] Do we still need mir-related components?

[binarman]

What?

I propose to delete https://github.com/Samsung/ONE/tree/master/compiler/mir and related components from source code.

Why?

This is an old part of the project, and I am not sure if someone still need this. It breaks time to time and requires maintenance.

Source itself is in the history and existing release archive files. It's OK for me to deprecate mir.

... It breaks time to time and requires maintenance.

@binarman , Is that a big burden? Does this module have no build dependencies from other modules we need? How about just excluding it from the default build target without deleting the source code? Of course, it will require a lot of modifications to use it again in the future.

We can revise CMake to skip the module if CMakeLists.txt is absent (by renameing it)
