Fix mux_acl_rule adding issue (sonic-net#2356)

What I did
This PR is to fix the issue of adding mux_acl_rule into IngressTableDrop.
The error log is

 Jun 25 08:02:37.159020 svcstr-7050-acs-4 ERR swss#orchagent: :- validateAclRuleMatch: Match SAI_ACL_ENTRY_ATTR_FIELD_IN_PORTS in rule mux_acl_rule is not supported by table IngressTableDrop
PR sonic-net#2341 added support for different matching field in different stage (INGRESS/EGRESS). For example, SAI_ACL_ENTRY_ATTR_FIELD_IN_PORTS is only supported at INGRESS stage.

However, PR sonic-net#2341 only handled one path for creating ACL table, that is by CONFIG_DB entry.
There is a case that addAclTable is directly called from other orch, such as MuxOrch. In that case, the stage dependent matcing field is not added. As a resule, we will see the above error logs.
To address the issue, I moved the call of addStageMandatoryMatchFields from doAclTableTask to addAclTable to ensure addStageMandatoryMatchFields is always called.
Please be noted that addMandatoryActions is called from both doAclTableTask and addAclTable to ensure the validation of ACL table is passing.

Why I did it
To fix ACL rule issue for mux.
