[PATCH] [Driver] Move description of toolchain specific include directories from the common driver code to the corresponding `MultilibSet` declarations

[Simon Atanasyan]

Hi rafael,

The patch moves description of toolchain specific include directories from the common driver code to the corresponding `MultilibSet` declarations.

The `MultilibSet` can hold an optional callback function which is responsible to return a set of include directories specific for the toolchain. That allows, for example, to remove MIPS toolchain specific directories from `Linux::AddClangSystemIncludeArgs` method and simplify adding new directories in the future.
