LOG: [ORC] Use MapperJITLinkMemoryManager for ReOptimizeLayerTest. (#163495)

This is an attempted fix for
https://github.com/llvm/llvm-project/issues/158270.

The issue described sounds like it may be caused by non-contiguous
regions returned for separate allocations by the default memory manager.
Using MapperJITLinkMemoryMnaager with a 10Mb slab size should fix the
issue.
