hle: Make Ryujinx.HLE project entirely safe (#2789)

Browse Source 
* Remove a bit of unsafety around

* Regenerate StructArrayHelpers with a max element value of 256

* hle: remove unsafe marker from all struct that had it

* hle: make SoftwareKeyboardRenderer.TryCopyTo safe

* hle: remove unsafety in NpadDevice and remove AllowUnsafeBlocks from csproj

* Revert "Regenerate StructArrayHelpers with a max element value of 256"

This reverts commit f32a6e5be0.

* Introduce ByteArray of various size and use that instead of ArrayXXX to avoid stackoverflow in .NET runtime type resolution

* Use ByteArray more

* Add some missing spaces on Pack = 1 for various structs

* Fix broken logic for TryCopyTo

* Address gdkchan's comment
