Obsolete function delegates

[SimonCropp]

BaseModuleWeaver has some technical debt. In earlier versions, before the FodyHelpers nuget and the existence of BaseModuleWeaver, weavers could be any type and duck typing was uses to set function delegates. When BaseModuleWeaver was added, there was a period where "any type" approach was supported, so weaver could optionally inherit from BaseModuleWeaver. This meant that the setting function delegates approach was also used for BaseModuleWeaver. Since weavers are now required to inherit from BaseModuleWeaver proper method, and overloads, can be used. As such the following methods have been obsoleted (with warning) and alternatives added.

• FindType => FindTypeDefinition
• TryFindType => TryFindTypeDefinition
• LogDebug => WriteDebug
• LogInfo => WriteInfo
• LogMessage => WriteMessage
• LogWarning => WriteWarning
• LogWarningPoint => WriteWarning
• LogError => WriteError
• LogErrorPoint = >WriteError
