WIP F# 5.x Proposal Main Theme - Struct, ByRef, and Span updates

Language

• Implicit conversion to inref<_> on method calls
• Static local functions via static let
• Local functions can have a byref-like parameter type
• Unmanaged constraint relaxation
• Add implicit conversion of types to Span / ReadOnlySpan on method calls. - needs proposal
• Function pointer (delegate pointer) support - needs proposal - needed to support native and C# interop - might require FSharp.Core additions
