net/bnxt: add conditional opcode and L4 port fields

The conditional field opcode provides capability to perform
changes to the field values specified by template to address
platform specific modifications. For instance, mirror id value
is modified before it is configured in the hardware.

The addition of L4 port compute fields enables support of
generic exact match rule that can support both TCP and UDP
flows with the same template.
