Backport of #116798 to release/10.0-preview7

Customer Impact
When users call
JsonValue.GetValue<T>orJsonValue.TryGetValue<T>, the call could fail due to being unable to convert the underlying type of theJsonValuetoT. This was caught through Compat Lab testing for preview 6 and they filed this issue for it: #116730. In their repro, they were trying to convert toGuid. This PR fixes the issue by using the same conversion logic that we use inJsonValueOfElementlike we did before the regression.Regression
This was introduced when #115856 was added. In that PR a new approach to creating primitive values was introduced but the
JsonValues that were created were not convertible viaGetValue/TryGetValue.Testing
The reported test case was added as a unit test and passes. The unit test coverage was expanded to fully cover the new code path.
Risk
Low. The fix uses the same conversion logic that we used prior to the regression. This is found here:
runtime/src/libraries/System.Text.Json/src/System/Text/Json/Nodes/JsonValueOfElement.cs
Line 60 in b131b6d
