[net10.0] [dotnet] Disable aggressive attribute trimming when using N…

…ativeAOT. Fixes #22065.

Aggressive attribute trimming removes attributes used by the trimmer. This is
fine as long as we don't run _two_ trimmers - because then the first pass
would remove attributes needed by the second pass, which is exactly what
happens when we're building using NativeAOT: we first run ILLink, then
NativeAOT's trimmer.

If aggressive attribute trimming is enabled in this scenario, ILLink will
remove attributes required by NativeAOT to work correctly, so disable
aggressive attribute trimming.

Fixes #22065.
