Remove qualifiers from lhs of sycl local variable declarations.

[kris-rowe]

Details

• Currently @shared declarations with qualifiers lead to compilation errors since we use auto&
• Example: @shared long int x[3] is translated to long auto& x = ... instead of auto& x = ...
• Qualifiers are still included in the template parameter of the RHS call for allocating local memory.
