[Mellanox] Update HW-MGMT package to new version V.7.0030.1011 (#16239)
- Why I did it
1. Update Mellanox HW-MGMT package to newer version V.7.0030.1011
2. Replace the SONiC PMON Thermal control algorithm with the one inside the HW-MGMT package on all Nvidia platforms
3. Support Spectrum-4 systems

- How I did it
1. Update the HW-MGMT package version number and submodule pointer
2. Remove the thermal control algorithm implementation from Mellanox platform API
3. Revise the patch to HW-MGMT package which will disable HW-MGMT from running on SIMX
4. Update the downstream kernel patch list

Subject: [PATCH backport 5.10 156/182] mlxsw: minimal: Add interfaces for line
card initialization and de-initialization
Add callback functions for line card 'netdevice' objects initialization
and de-initialization. Each line card is associated with the set of
'netdevices', which are created/destroyed dynamically, when line card
is getting to active / inactive states.
Add APIs for line card registration and de-registration during init and
de-init.
