9b26e96b11 Do not copy std::vector of OS handles when it is not needed 
This change replaces unneeded copying of std::vectors
with usage of const references. Furthermore, it adds
reserve() call before filling the container via push_back().

a3b3f3e86e Add support for PRELIM_I915_PARAM_SET_PAIR 
This extension allows pairing two buffer objects so they can be
exported using a single dma-buf handle. When imported, a single
buffer object is created with a total size of the two buffer
objects.

3f26f45c10 Add support for IPC handles with implicit scaling 
When using implicit scaling, device allocations may have
more than one internal allocation created internally. In that case,
a separate dma-buf handle per internal allocation needs to be
exported.

So introduced two driver experimental extensions to export and
import more than one IPC handle:

- zexMemGetIpcHandles
- zexMemOpenIpcHandles
