Suggestion: support C# collection expressions for creating `VariableLengthInlineArray`s

Is your feature request related to a problem? Please describe.
When using CsWin32 to call the AdjustTokenPrivileges API, it took me a little while to realize how to create a new VariableLengthInlineArray (partly due to my lack of experience with ref types in C#).
Even after finding it out, I think that having to create an inline array by using an object initializer or assigning each member manually is quite unintuitive. It would be better if the library allowed to create such arrays using collection expressions introduced in C# 12.

Describe the solution you'd like
Instead of having to use this syntax to instantiate a VariableLengthInlineArray

var array = new VariableLengthInlineArray<Struct> {
    [0] = new Struct(),
    [1] = new Struct()
}

I'd like to be able to do it like this:

VariableLengthInlineArray<Struct> array = [new Struct(), new Struct()]

Start by locating the generation and supporting-type implementation for VariableLengthInlineArray, then inspect any tests covering its current object-initializer or indexed-assignment syntax. Add coverage showing that C# 12 collection expressions create the array, while confirming the existing initialization behavior remains supported.
