Add Guid.GetBytes(byte[]) and Decimal.GetBits(decimal d, byte[]) #18969
Description

Today the supported way to get the byte[] representation of a guid is to use ToByteArray() https://github.com/dotnet/coreclr/blob/master/src/mscorlib/src/System/Guid.cs#L893, which allocates a byte[]. Instead it would be great if there was an overload that could write into an existing byte[]

Guid.GetBytes(Span<byte>)?

Would be even better. When Span<T> exists
