net/mlx5e: TC, rename post_meter actions

Browse source 
Currently post meter supports only the pipe/drop conform-exceed policy.
This assumption is reflected in several variable names.
Rename the following variables as a pre-step for using the generalized
branching action platform.

Rename fwd_green_rule/drop_red_rule to green_rule/red_rule respectively.
Repurpose red_counter/green_counter to act_counter/drop_counter to allow
police conform-exceed configurations that do not drop.
