[ptensor] add missing elementwise binary operations

[fschlimb]

The following elementwise binary operations need an implementation in PTensorToLinalg(.cpp) (see array-API spec for the expected behavior of the operations):

• ptensor::ATAN2
• ptensor::LOGADDEXP
• ptensor::LSHIFT
• ptensor::MATMUL
• ptensor::TRUE_DIVIDE
• ptensor::BITWISE_AND
• ptensor::BITWISE_LEFT_SHIFT
• ptensor::BITWISE_OR
• ptensor::BITWISE_RIGHT_SHIFT
• ptensor::BITWISE_XOR
• ptensor::EQUAL
• ptensor::GREATER
• ptensor::GREATER_EQUAL
• ptensor::LESS
• ptensor::LESS_EQUAL
• ptensor::LOGICAL_AND
• ptensor::LOGICAL_OR
• ptensor::LOGICAL_XOR
• ptensor::NOT_EQUAL

See also Operation Details->Elementwise Operations in the RFC.

Reference implementations can be found in the TOSA dialect and/or on main (numba_dpcomp/numba_dpcomp/mlir/numpy/funcs.py [Python]).

It is ok to let initial implementations operate on default PTensorTypes only, e.g. ignore device and distribution attributes of input tensors.
