Update GCInfo deserializer once https://github.com/dotnet/runtime/pull/104336 merges

[VSadov]

dotnet/runtime#104336 changes the encoding of GC info in a breaking way.
(arm/arm64 code offsets are encoded with fewer bits)

Once the runtime change goes in, the SOS copy will need to be updated correspondingly, to be able to dump from GcInfo v3

@VSadov is the reverted runtime change going to eventually make it into .NET 9? Can I change this issue to .NET 10?

[VSadov]

Pushed out to dev10.
Sorry, I forgot to change this issue once it was clear it is not going to make it into 9.

[VSadov]

Hmm, it does not look like i can change the milestone.

The GCInfo change was merged into .NET 10 main. The commands to dump GCInfo are broken in SOS as of right now.

[mikem8361]

Now that the GC commands have been rewritten in C# and use CLRMD, this is problem a change in CLRMD.

This is about https://github.com/dotnet/diagnostics/blob/main/src/shared/vm/gcinfodecoder.cpp and related files. Was this decoder rewritten in C#? I am not aware of it.
