Bugfix/missing attributes for dynamic proxy

[huoshan12345]

1. replicate attributes that are targeted on implementation type to proxy type in method ProxyGeneratorUtils.CreateClassProxyInternal, which is used in method ProxyGenerator.CreateClassProxy<T>()
2. add tests for 2#
3. fix typo CustomAttributeBuildeUtils -> CustomAttributeBuilderUtils
4. typeof(IAspectValidator).Name -> nameof(IAspectValidator)

Here is a related question:
Do we need to replicate attributes(targeted on type, property, method) from implementation type to proxy type that are created in ProxyGeneratorUtils.CreateInterfaceProxyInternal, which is used in ProxyGenerator.CreateClassProxy<TService, TImplementation>?

Currently,

1. all the attributes from TService are replicated to proxy type.
2. none of the attributes from TImplementation is replicated to proxy type.

Personally, I think we can follow the same logic as TService service = new TImplementation().
In other words,

1. donot replicate any attributes from TService to proxy type, which should be inherited to proxy type.
2. replicate all the attributes from TImplementation to proxy type.
