Inconsistent mapping for MapProperty when Source or Target properties are ignored

[TimothyMakkison]

Describe the bug
MapProperty maps MapperIgnoreSource properties but will not map MapperIgnoreTarget properties.

To Reproduce

[Mapper]
public static partial class Mapper
{
    [MapperIgnoreSource("Value")]
    // [MapperIgnoreTarget("Dest")]
    [MapProperty("Value", "Dest")]
    public static partial B IgnoredSource(A src);

    // [MapperIgnoreSource("Value")]
    [MapperIgnoreTarget("Dest")]
    [MapProperty("Value", "Dest")]
    public static partial B IgnoredTarget(A src);
}
public record A
{
    public int Value { get; set; }
}
public record B
{
    public int Dest { get; set; }
}

public static partial global::B IgnoredSource(global::A src)
{
    var target = new global::B();
    target.Dest = src.Value;
    return target;
}

public static partial global::B IgnoredTarget(global::A src)
{
    var target = new global::B();
    return target;
}

Expected behaviour
Mapperly should either not map when MapperIgnoreTarget is used or it should map when mapping from an ignored source property.
If we change Mapperly to map ignored properties then it should create a warning stating that ignoring the property is unneeded and has been overwritten.
