[ORC][COFF] Remove the ExecutionSession& argument to COFFPlatform factory & constructor (llvm#112419)

We can get a reference to the `ExecutionSession` from the
`ObjectLinkingLayer` argument, so there's no need to pass it in
separately.

This mirrors recent changes to `ElfNixPlatform` and `MachOPlatform` by
@lhames in
llvm@3dba4ca
and
llvm@cc20dd2.
