[DASH] New test cases for dash acl tag (sonic-net#11559)

- What is the motivation for this PR?
Add new test cases for dash acl tag feature

- How did you do it?
All new test cases are added to the test_dash_acl.py and dash_acl.py.
For the scale test case, need to do some improvement in the dash acl test infra and dash gnmi utils to allow applying massive configurations through gnmi and shorten the config time.

The improvements are:
1. Separate the gnmi command into multiple commands if it is too long, for there is a limitation in the length of command.
2. Directly copy the updates to ptf instead of to dut. Since we are now using gnmi, no need to copy the config to dut, this will greatly reduce the config time.
3. Tar the update files before copying them to save great time.

Note:
For the scale test case, only test 4096 tags with 1 IP address in each, due to issue [DPU][ACL][scale] The DPU doesn't support the scale of 4k tags with 24k IPs in each sonic-buildimage#17714.

- How did you verify/test it?
Run the test cases on DPU testbed, all passed.

- Any platform specific information?
Only for dpu.

- Supported testbed topology if it's a new test case?
Only for dpu topology.
