Load a ELF file.

@param[out] EntryPoint Will be filled with the ELF entry point address.
@param[out] ImageSize Will be filled with the ELF size in memory. This will
effectively be equal to the sum of the segments sizes.
This function assumes the header is valid and supported as checked with

- We don't currently take the segment permissions into account (indicated by
the program headers). It can be used to allocate pages with the right
read/write/exec permissions.
