[gcu]: Add marvell-teralynx platform to gcu field validator

[rminnikanti]

Fixes #3883

What I did

Enable BUFFER_PROFILE replace operation on dynamic_th field and
PFC_WD field operations on marvell-teralynx platform starting 20241100 Sonic version

How I did it

Added marvell-teralynx platform name to gcu_field_operation_validators.conf.json.

How to verify it

cat buffer_profile.json
[
  {
     "op": "replace",
     "path": "/BUFFER_PROFILE/pg_lossless_50000_5m_profile/dynamic_th",
     "value": "2"
  }
]

Verify above configuration on marvell-teralynx platform using below command:

config apply-patch buffer_profile.json
