Enhancement: Parallelize plugin builds, use docker layer caching

[prasadlohakpure]

This pull request updates the plugin build process in the build.sh script to improve build performance and provide clearer build output. The most important change is the use of parallel execution for building plugins and adding a log message for each plugin being built.

Build process improvements:

• Modified the plugins build command in build.sh to use xargs -P 0 for parallel building of plugins, which speeds up the build process.
• Added an echo statement to log the name of each plugin as it is being built, providing clearer feedback during the build.
• Added docker layer build caching to reduce time taken in incremental builds.

Results

• Before(with UI build disabled, simply benchmarking go builds)
  ./build.sh 41.18s user 13.05s system 89% cpu 1:00.64 total

• After
  ./build.sh 55.11s user 19.25s system 198% cpu 37.416 total
  193% cpu usage suggests build generation utilised multiple cores
  Savings in build time: ~40%
