Update 7260 MMU and ECN settings (#11449)

Signed-off-by: Neetha John <nejo@microsoft.com>

Why I did it
Improve throughput and latency for 7260 deployments

How I did it
Update the dynamic threshold to 0 and ECN settings as 2mb/10mb/5%

How to verify it
Updated unit tests to use the modified values for 7260 ecn settings.
