Record structs with InlineArray attribute compares only by the first value.

[Ilchert]

Related to the dotnet/runtime/issues/96943.

Version Used:
dotnet SDK 8.0.204

Steps to Reproduce:

1. Create record struct with InlineArray attribute
2. Call equals.
3. Record structs with InlineArray attribute compares only by the first value.

var a1 = new A();
a1[0]=1;
a1[1]=2;

var a2 = new A();
a2[0] = 1;
a2[1] = 1;


Console.WriteLine(a1.Equals(a2));

[InlineArray(2)]
record struct A
{
   public int P;
}

Expected Behavior:
Should compare all values in inline array and print false in this case.

Actual Behavior:
Compares only the first element.

This combination of features (record and InlineArray) is not particularly useful. @AlekseyTs did we consider making this combination an error at declaration? Can't see any good reasons to allow this.

This is an oversight, there was no intent to support record-like behavior for inline arrays.
