## Details
After migrating to engine python environment, there is no extra step required to launch resource mapping tool in editor.
1. This change is to migrate the editor tool launching process to engine python environment.
2. Add messagebox to show errors while using the tool
3. Note - as Qt binaries are not well organized in build directory, so separate out *AWSCore.ResourceMappintTool* target to group Qt binaries into independent build sub folder to solve the issue (temporarily, fix can be tracked by https://jira.agscollab.com/browse/LYN-2669, once fix is done, we can just remove this individual target)
