Update SDK/FW to version 4.5.4206/4.5.4204 (sonic-net#14164)

- Why I did it
To include latest fixes:

Fix traffic loss on all routed traffic when moving from 4.4.3372/XX_2008_3388 to 4.5.4118-012/XX_2010_4120-010. Issue occurred after ISSU process in Spectrum 1 only, When upgrading from older version to a new one. Neighbor entries are overwritten.
Fix When using mirror session policer on SPC2/3, the actual CIR was 1.28 times more than the configured CIR value.
Fix Creation of router interface of type bridge may occasionally fail if create is performed immediately after delete.
Fix False errors during SDK deinitialization may be seen in the syslog

- How I did it
Updated SDK submodule and relevant makefiles with the required versions.

- How to verify it
Build an image and run tests from "sonic-mgmt".
