Revert "Remove InternalsVisibleTo attributes for .NET MAUI Community … (dotnet#34047)

### Description of Change

This reverts commit 8e96657. (from
dotnet#33442)

Context :  dotnet#29321 

> Revert for now because the timing doesn't line up yet. We don't have a
version of the Toolkit that uses the public types so with this change,
the .NET 10 preview templates (using --sample-content) using the Toolkit
will break immediately.

This is still not true as per the time we're discussing this, so there's
no good reason to introduce those changes (from dotnet#33442) in a service
release, as this is a massive breaking change. Making the version
unusable for everyone using the toolkit.

Not to mention that 10.0.40 has some important bug fixes related to
different crashes, which makes this situation quite annoying

### Issues Fixed

Fixes dotnet#34035 
Fixes dotnet#34034 
Fixes dotnet#34048 

#### Toolkit issues related
