Add gearbox phy device files and a new physyncd docker to support VS gearbox phy feature (#4851) 
* buildimage: Add gearbox phy device files and a new physyncd docker to support VS gearbox phy feature

* scripts and configuration needed to support a second syncd docker (physyncd)
* physyncd supports gearbox device and phy SAI APIs and runs multiple instances of syncd, one per phy in the device
* support for VS target (sonic-sairedis vslib has been extended to support a virtual BCM81724 gearbox PHY).

**- Why I did it**

This work is part of the gearbox phy joint effort between Microsoft and Broadcom, and is based
on multi-switch support in sonic-sairedis.

**- How I did it**

Overall feature was implemented across several projects. The collective pull requests (some in late stages of review at this point):

https://github.com/Azure/sonic-utilities/pull/931 - CLI (merged)
https://github.com/Azure/sonic-swss-common/pull/347 - Minor changes (merged)
https://github.com/Azure/sonic-swss/pull/1321 - gearsyncd, config parsers, changes to orchargent to create gearbox phy on supported systems
https://github.com/Azure/sonic-sairedis/pull/624 - physyncd, virtual BCM81724 gearbox phy added to vslib

**- How to verify it**

In a vslib build:

root@sonic:/home/admin# show gearbox interfaces status
  PHY Id    Interface        MAC Lanes    MAC Lane Speed        PHY Lanes    PHY Lane Speed    Line Lanes    Line Lane Speed    Oper    Admin

In addition, docker ps | grep phy should show a physyncd docker running.
