[fpc-pascal] Add API to official documentation search

[Ryan Joseph]

Could FPC make an API for the official documentation search at https://www.freepascal.org/docsearch/docsearch.var so we could make calls like:

https://www.freepascal.org/docsearch/docsearch.var?word=List

and get back a JSON object that had the search results? This is important for integration with 3rd party IDE's.
