Feature: Updated LPE Packager with Auto-version update publish support + misc. improvements

[kjohn-msft]

Packager updates pulled out to code base debt erasure (and revised a little further):
#224

Changes in this PR:

1. Addition of build.bat / .sh in the src folder to package all components. [Builds without version change]
2. Addition of publish.bat / .sh in the src folder to increment the manifest version and package all components. (reduces friction in PR for publish, i.e. new branch -> publish (at prompt) -> push branch -> PR) [Builds with automatic version increase]
3. Removal of version information from multiple places and centralizing to the manifest source of truth that gets used in packaging.
4. Moved packager scripts to a packager sub-folder. Updated references. This will be reflected in the internal make file.
5. Updated component naming to reduce confusion in multi-extension support scenarios.
6. Cleanup output and removed misc. debt.
