Code is not correctly generated when using directives are wrapped with #if and #endif

[Haruma-K]

We encountered an issue where generated code results in compilation errors when using directives are conditionally included using #if / #endif.

Here is a minimal reproducible example:

#if !MASTER_MEMORY_DISABLED
using MasterMemory;
using MessagePack;
#endif

namespace Example1
{
#if !MASTER_MEMORY_DISABLED
    [MemoryTable("person")]
    [MessagePackObject(true)]
#endif
    public record Person
    {
#if !MASTER_MEMORY_DISABLED
        [PrimaryKey] 
#endif
        public int Id { get; set; }
    }
}

When using this pattern, the generated code causes compilation errors with the following messages:

MasterMemory.SourceGenerator/MasterMemory.SourceGenerator.MasterMemoryGenerator/MasterMemory.DatabaseBuilder.g.cs(29,2): error CS1027: #endif directive expected
MasterMemory.SourceGenerator/MasterMemory.SourceGenerator.MasterMemoryGenerator/MasterMemory.ImmutableBuilder.g.cs(64,2): error CS1027: #endif directive expected
MasterMemory.SourceGenerator/MasterMemory.SourceGenerator.MasterMemoryGenerator/MasterMemory.MemoryDatabase.g.cs(129,2): error CS1027: #endif directive expected
MasterMemory.SourceGenerator/MasterMemory.SourceGenerator.MasterMemoryGenerator/MasterMemory.MasterMemoryResolver.g.cs(70,2): error CS1027: #endif directive expected
MasterMemory.SourceGenerator/MasterMemory.SourceGenerator.MasterMemoryGenerator/MasterMemory.PersonTable.g.cs(105,2): error CS1027: #endif directive expected

We’d appreciate it if you could take a look and consider supporting this pattern.
