doc: Migrate content from User Guide and update it

The User Guide document holds many different bits of
information that are not always related to each other. These
are moved out into files where information is grouped tightly
together.

This also updates build instructions and environment variable
instructions to link to the relevent parts of the TF-A user guide
and use more recent versions of compiler, respetively.
