Add nativefilestream and several new methods to File and FileStream

[josesimoes]

Description

• Add native file stream.
• Add new methods to File and FileStream.
• Major rework on existing code to use these new APIs.
• Remove a few methods that now exist on .NET aligned API.
• Remove several properties and methods that are unlikely to have any use (or hard to implement) in embedded systems context.
• Improve/fix Intellisense comments.
• Bump native assembly version.

Motivation and Context

• Need to improve file access performance.
• Need implementation to offer file access control/share between threads.
• Need some APIs that are handy for basic file operations.
• Improve alignment with .NET API.

How Has This Been Tested?

• Unit tests being added and integration tests with real hardware. Testing in ORGPAL targets. FatFS and littlefs file systems in 2 different flash (Q)SPI chips, SD card and USB MSD.

nice heavy lifting, couple of quick comments

[MrCSharp22]

Looks good to me. A few comments but nothing major. Thanks :)

I have added a couple of comments regarding the native methods (as yet unimplemented). I feel that it might be advantagous to change the types of at least offset and count to better check that they "will" be valid as should always be a positive value. We also need to check whether they are in a valid range (offset + count cannot be greater than the file size).

The type being unsigned should also improve RAM allocation.
