[main] Update dependencies from dotnet/arcade mono/linker

- cherry-pick of a5dbede / #7531

When comparing definitions this was failing if the type couldn't be resolved,
for instance if a type-forwarded dependency was missing or references
were specified at all.

This was inconsistent with our other parameter comparisons which just
evaluate the compare the type reference as a string without considering
assembly.

This does raise a concerning issue, that APICompat doesn't actually
evaluate assembly equivalence of parameters but that's an existing
problem.

- use `Get-Member` instead of assuming `$null` property value
- fixes build break I caused in 13040ff
