scripts: add oe-build-perf-report script
A new tool for pretty-printing build perf test results stored in a Git repository. The scripts is able to produce either simple plaintext report showing the difference between two commits, or, an html report that also displays trendcharts of the test results. The script uses Jinja2 templates for generating HTML reports so it requires python3-jinja2 to be installed on the system.
