Since sm_6_5 is the new default, remove the -use-dxil option, add -use-dxcb option Remove -use-dxil option from all test cases. Add -use-dxcb to two tests that needed it.

Unlike DXIL, stripping the Slang IR for a function down to a declaration requires retaining a block of parameters, as the function declaration must be emitted to SPIR-V with the same parameters as a definition. Because that thwarts the logic in Slang to tell the difference between a declaration and definition, and explicit decoration is introduced to explicitly mark functions which need to be treated as declarations during emit phase.
