Crash during aovInputTask on Intel mac with Radeon Pro 560

[schevrel]

Description of Issue

On Intel Mac with Radeon Pro 560, during the aovInputTask texture creation for the depth buffer, the following error is printed and the texture creation crashes.

-[MTLTextureDescriptorInternal validateWithDevice:] failed assertion Texture Descriptor Validation MTLTextureDescriptor: Depth, Stencil, DepthStencil textures cannot be allocated with MTLStorageModeShared or MTLStorageModeManaged on this device.

It seems that the issue was introduced with #3215, by this line:
/~https://github.com/PixarAnimationStudios/OpenUSD/blob/release/pxr/imaging/hgiMetal/texture.mm#L27

When the resourceOptions is MTLResourceStorageModePrivate it works on that platform.
