…sources that are CPU accessible. (microsoft#22680)

Adjust max chunk size to fix error limit check from DX12 for large
resources that are CPU accessible.

### Description
Current agility SDK restricts CPU visible buffers to 0xFFFF0000 bytes or
slightly smaller than 4GiB. Verified restriction is still in latest
Agility SDK 1.614.1.


### Motivation and Context
Allocation of Resources 4GiB or larger fail in DX12 verification layer.
