Support for Nvidia AGX Thor

[TangmereCottage]

• In the standard cloud confidential computing setup, an Intel CPU supporting TDX is used in concert with an Nvidia GPU, such as the H100/H200.

• The new Nvidia AGX Thor does not have an Intel CPU, but a custom ARM CPU - the 14-core ​​Arm® Neoverse®-V3AE 64-bit CPU​​.

• That uses the 'Arm Confidential Computing Architecture' and the 'Armv9.2-A Realm Management Extension' (RME)

• Are there plans to add support for the Arm CC to Dstack? If so, do you need help with that?

ARM CC support isn't planned for the immediate future. The matter remains open for discussion.
