webnn: Use newer DirectML CLIP operator when possible
Uses DML_ELEMENT_WISE_CLIP1_OPERATOR_DESC to implement the clamp
operator instead of DML_ELEMENT_WISE_CLIP_OPERATOR_DESC when the DML
feature level is high enough
The key difference between these operators is that the older operator
always takes min and max values as float32 values and internally
casts to the appropriate data type, whereas the newer operator allows
passing min and max values as the same data type as the input and
output tensors
This moves the casting logic to the caller (us!) so this CL adds WPT
conformance tests for all data types which the DML backend supports
to ensure the explicit casting added in this CL works as expected
