This patch add DXC compile flag "-enable-16bit-types" and change profile to SM6.2 when validating generated HLSL using DXC if f16 extension is enabled in the WGSL program. The patch add Tint end-to-end test cases for expressions using f16 type, including constructor, binary operator, splat, zero-init, and others. Testcases that use f16 types in uniform or storage buffer are SKIPped, because such usage is not implemented yet.
