Reviewed by Tadeu Zagallo.

Add support for transient attachments, which are beneficial for helping reduce 
jetsams on iOS due to memory pressure.

Prior to this change, 
https://gpuweb.github.io/cts/standalone/?q=webgpu:api,validation,createTexture:depthOrArrayLayers_and_mipLevelCount_for_transient_attachments:*
would print "TRANSIENT_ATTACHMENT is not supported"

WKTR treats both skipped and passing tests as 'PASS' so -expected.txt files did 
not change.
