Deconstruct extension for KeyValuePair<TKey, TValue>

[Arthri]

Description (optional)

Add an extension to KeyValuePair<TKey, TValue> that mirrors https://learn.microsoft.com/en-US/dotnet/api/system.collections.generic.keyvaluepair-2.deconstruct?view=net-7.0

Rationale

The extension allows for KeyValuePairs to be deconstructed in scenarios such as

foreach ((var k, var v) in dict)
{
    // ...
}

Proposed API

https://learn.microsoft.com/en-US/dotnet/api/system.collections.generic.keyvaluepair-2.deconstruct?view=net-7.0 Allows the compiler to deconstruct KeyValuePairs in tuple patterns or other tuple-like scenarios
