IntelFsp2Pkg: Add search function for Config Editor

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3482

This patch adds a search function in the Config Editor GUI at
the top right corner. Once users key in the words to search,
it will look for the option containing the string in the
same page and display it. It also includes a README for this
function.
