Global: Remove project specific implementation of NewElement1D & NewElement0D

#### Parent issue(s) or Pull Request(s) causing the changes:

#1787
Not removed in said PR to avoid unneeded conflicts in `.csproj`

#### Description:

Remove project specific implementation of the NewElement1D & NewElement0D methods in:

- [ ] Architecture_Engine
- [ ] Environment_Engine
- [ ] Physical_Engine
- [ ] Structure_Engine

#### Test file(s):

Review the NewElement1D and NewElement0D implementations in the Architecture_Engine, Environment_Engine, Physical_Engine, and Structure_Engine projects, along with their .csproj files and parent issue #1787. Done means the project-specific implementations are removed without unnecessary project-file conflicts; no test file is named, so identify the relevant validation before changing anything.
