…or active ports without speed configured (sonic-net#1822)

**What I did**
Bugfix: Don't create lossless buffer profiles for active ports without speed configured

Root cause:
- In `handlePortTableUpdate`, `refreshPgsFromPort` is called if admin status is updated even if the speed is not configured.
  This is reasonable because the port can be configured as headroom override and the profile should be applied in that case.
- However, as a side-effect, the port's state is set to `PORT_READY` in `refreshPgsForPort` regardless of whether the speed is configured, which is not correct.
  This should be avoided and `PORT_READY` should be set by the caller if necessary

Fix:
- Don't set the port's state to `PORT_READY` in `refreshPgsForPort` and check the port's state before calling it.
- Explicitly set port's state to `PORT_READY` in `handlePortStateTable`. This has been done by all other callers.

Note:
- The change is covered by the existing vs tests.
- The scenario where the bug was originally found can not be covered by vs test because:
  - The speed is always configured in vs image by default
  - Removing speed is not handled in buffer manager since it's not a valid flow.
- A regression test will be opened to cover this case.

…uffer for unused ports (sonic-net#1822)

Signed-off-by: Stephen Sun [email protected]

What I did
Db migrator support reclaiming reserved buffer for unused ports

How I did it
For admin down ports, if the buffer objects configuration aligns with default configuration, set the buffer objects configuration as:

Dynamic model: all normal buffer objects are configured on admin down ports. Buffer manager will apply zero profiles on admin down ports.
Static model: zero buffer objects are configured on admin down ports.

How to verify it
Unit test.
Manually test.
