  Update Developer Policy for copyright notices (#123463)

This updates the developer policy to align with established community
norms for copyright notices in source code contributed to LLVM.

The updates clearly state that we do not accept code contianing explicit
copyright notices in source except where such code is a pre-existing
part of an external dependency that is being vendored into LLVM.

Explicit copyright notices in source add no value to the project since
copyright ownership is well tracked through git. Our policy already
requires that contributions made not by the original author have
appropriate attribution in git commit messsages or metadata.

Further, explicit copyright notices in code can easily get out of date
as the code is refactored, updated by additional authors or otherwise
changed over time. This leads to misleading out-of-date copyright
notices which do more harm than good.

This change should be viewed as a clarification and statement of
existing established policy, not a change in policy since it represents
the way the project has been operating.
