Align MemoryStream Position and Seek to mention origin on ArgumentOutOfRangeException

MemoryStream was recently fixed to avoid falling into a state where it could contain a negative `Position` https://github.com/dotnet/runtime/pull/88572.

Some API docs don't mention the `origin` when they talk about ArgumentOutOfRangeException and only mention that the value must be between int.MaxValue and zero.
* [Seek()](https://learn.microsoft.com/en-us/dotnet/api/system.io.memorystream.seek?view=net-7.0#exceptions)
* [Position](https://learn.microsoft.com/en-us/dotnet/api/system.io.memorystream.position?view=net-7.0#exceptions)

[SetLength](https://learn.microsoft.com/en-us/dotnet/api/system.io.memorystream.setlength?view=net-7.0) does correctly reflect that the limit accounts for the origin:
> value is negative or is greater than the maximum length of the MemoryStream, where the maximum length is (Int32.MaxValue - origin), and origin is the index into the underlying buffer at which the stream starts.

We need to amend the former cases to align with SetLength's.
