Why I did it
This PR is to backport #11569 into 202012 branch.
This PR is to apply different DSCP_TO_TC_MAP to downlink and uplink ports on T1 in dualtor deployment.
For T1 downlink ports (To T0)
The DSCP_TO_TC_MAP is not changed. DSCP2 and DSCP6 are mapped to TC2 and TC6 respectively.
For T1 uplink ports (To T1)
A new DSCP_TO_TC_MAP|AZURE_UPLINK is defined and applied. DSCP2 and DSCP6 are mapped to TC1 to avoid mixing up lossy and lossless traffic from T2.
The extra lossy PG2 and PG6 added in PR #11157 is reverted as well because no traffic from T2 is mapped to PG2 or PG6 now.
How I did it
Define a new map DSCP_TO_TC_MAP|AZURE_UPLINK for 7260 T1.
How to verify it
Verified by test case in test_j2files.py.

Why I did it
As part of PCBB changes, we need to enable 2 extra lossless queues. The changes in this PR are done to adjust only the reserved sizes on Th2 for the additional 2 lossless queues
Calculations are done based on 40 downlinks for T1 and 16 uplinks for dual ToR
How to verify it
Verified that the rendering works fine on Th2 dut
Unit tests have been updated to reflect the modified buffer sizes when pcbb is enabled. There are existing testcases that will test the original buffer sizes when pcbb is disabled. With these changes, was able to build sonic-config-engine wheel successfully

* [Tunnel PFC] Add property for tunnel PFC
Replace the config.bcm file with j2 template file
- Add 'sai_remap_prio_on_tnl_egress=1' property when device metadata local
- Host subtype is 'dualtor'
- Change sai.profile foe the new config.bcm.j2
Set sai_tunnel_underlay_route_mode attribute to fallback to default
route if more specific route is unavailable.

This is to address an issue where it was observed that SAI operations sometime make take a very long to time complete (over 45ms). It was determined that the ALPM distributed thread was causing this issue.
The fix is to disable this debug thread that has no functional purpose.
Preliminary tests looks fine. BGP neighbors were all up with proper routes programmed
interfaces are all up
Manually ran the fib test cases on 7050CX3 (TD3), TD2, TH, TH2, and TH3 based platforms and
thy all passed.
Why I did it
Arista-7260CX3-Q64 is missing T1 MMU configuration.
How I did it
Define T1 MMU configuration for Arista-7260CX3-Q64.

* [202012] Add SOC property to enable AN/LT on some platforms
Why I did it
To enable autonegotiation/link training on some Broadcom-based platforms (Arista 7060CX, 7260CX3, 7050cx3, Celestica DX010)
How I did it
Add appropriate SOC property for enabling the feature to the Broadcom config files of appropriate platforms
Also convert line endings to UNIX format for one Celestica file
* Add 'phy_an_lt_msft' to BCM config file permitted list
* 7260cx3 DualToR config.bcm support based on DualToR setting in device metadata at boot time.
For HWSKU Arista-7260CX3-C64 the MMU setting SOC for T0/T1 is also combined into the config.bcm.j2 logic so use just one config file and adding delta based on Switch Roles.
However in SAI 3.7 default behaviout got changes to 128 Group and 128
Memeber each.
This change is to make sure we are using same ECMP Group/Memeber Per
Group for 3.7 also so that behaviour is consistent.
