Fix GpuArrayRemove to fallback for unsupported element types (#14129)

Restrict ArrayRemove TypeSig to exclude BINARY, ARRAY, STRUCT, and MAP
element types. cuDF's equalToNullAware does not support these types in
binaryOp, causing CudfException at runtime. Unsupported types now
correctly fall back to CPU execution.

Closes #14129
