* 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.

Overall goal: Build debug images for every stretch docker.
An earlier PR (#2789) made the first cut, by transforming broadcom/orchagent to build target/docker-orhagent-dbg.gz.
Changes in this PR:
Made docker-orchagent build to be platform independent.
1.1) Created rules/docker_orchagent.mk
1.2) Removed platform//docker-orchagent-*.mk
1.3) Removed the corresponding entry from platform//rules.mk
Extended the debug docker image build to stretch based syncd dockers.
2.1) For now, only mellanox & barefoot are stretch based.
2.2) All the common variable definitions are put in one place platform/template/docker-syncd-base.mk
2.3) platform/[mellanox, bfn]/docker-syncd-[mlnx, bfn].mk are updated as detailed below.
2.3.1) Set platform code and include template base file
2.3.2) Add the dependencies & debug dependencies and any update over what base template offers.
Extended all stretch based non-platform dockers to build debug dockers too.
3.1) Affected are:
docker-database.mk,
docker-platform-monitor.mk,
docker-router-advertiser.mk,
docker-teamd.mk,
docker-telemetry.mk
Next: Build debug flavor of final images with regular dockers replaced with debug dockers where available.
