[Mellanox] Fix for all Spectrum based systems: SAI profile speed configurations (#7119)
Fix to the correct value for all SPC1 devices.
For 10G added 10GB_CX4_XAUI, 10GB_KX4, 10GB_KR, 10GB_SR and 10GB_ER_LR
For 50G added 50GB_SR2

This bitmask represents all the options available for interface type and some were missing.
Note: it was working just fine if you were setting the value from SONiC CLI but not from the default SAI Profile.

[DPB] [Mellanox] added capability files for SN2700 platform (#6003)
[DPB] added capability files for SN2700 platform

- Why I did it
platform.json and hwsku.json files are required for a feature called Dynamic Port Breakout

- How I did it
Created capability files according to platform specification SN2700

- How to verify it
Full qualification requires bugs fixes reported under sonic-buildimage

NOTE: breakout to 4 is currently not available as of missing functionality in DPB implementation.

[Dynamic buffer calc] Support dynamic buffer calculation (#6194)
**- Why I did it**
To support dynamic buffer calculation.
This PR also depends on the following PRs for sub modules
- [sonic-swss: [buffermgr/bufferorch] Support dynamic buffer calculation #1338](https://github.com/Azure/sonic-swss/pull/1338)
- [sonic-swss-common: Dynamic buffer calculation #361](https://github.com/Azure/sonic-swss-common/pull/361)
- [sonic-utilities: Support dynamic buffer calculation #973](https://github.com/Azure/sonic-utilities/pull/973)

**- How I did it**
1. Introduce field `buffer_model` in `DEVICE_METADATA|localhost` to represent which buffer model is running in the system currently:
    - `dynamic` for the dynamic buffer calculation model
    - `traditional` for the traditional model in which the `pg_profile_lookup.ini` is used
2. Add the tables required for the feature:
   - ASIC_TABLE in platform/\<vendor\>/asic_table.j2
   - PERIPHERAL_TABLE in platform/\<vendor\>/peripheral_table.j2
   - PORT_PERIPHERAL_TABLE on a per-platform basis in device/\<vendor\>/\<platform\>/port_peripheral_config.j2 for each platform with gearbox installed.
   - DEFAULT_LOSSLESS_BUFFER_PARAMETER and LOSSLESS_TRAFFIC_PATTERN in files/build_templates/buffers_config.j2
   - Add lossless PGs (3-4) for each port in files/build_templates/buffers_config.j2
3. Copy the newly introduced j2 files into the image and rendering them when the system starts
4. Update the CLI options for buffermgrd so that it can start with dynamic mode
5. Fetches the ASIC vendor name in orchagent:
   - fetch the vendor name when creates the docker and pass it as a docker environment variable
   - `buffermgrd` can use this passed-in variable
6. Clear buffer related tables from STATE_DB when swss docker starts
7. Update the src/sonic-config-engine/tests/sample_output/buffers-dell6100.json according to the buffer_config.j2
8. Remove buffer pool sizes for ingress pools and egress_lossy_pool
   Update the buffer settings for dynamic buffer calculation

Support single ingress pool for MSFT SKUs and optimize headroom calculation (#4686)
Calculate pool size in t1 as 24 * downlink port + 8 * uplink port

- Take both port and peer MTU into account when calculating headroom
- Worst case factor is decreased to 50%
- Mellanox-SN2700-C28D8 t0, assume 48 * 50G/5m + 8 * 100G/40m ports
- Mellanox-SN2700 (C32)
  - t0: 16 * 100G/5m + 16 * 100G/40m
  - t1: 16 * 100G/40m + 16 * 100G/300m
