ref-manual: Updates to FILESPATH and FILESOVERRIDES.
Fixes [YOCTO #13112]
Did some paragraph re-ordering based on reviewer feedback.
Also, added a bit in the FILESOVERRIDES variable description
about out it uses overrides to help with automatic overriding
of the FILESPATH variable. Added some better links into the
BitBake User Manual as well.
(From yocto-docs rev: 6ad5c6f030501cda9bc8ea648d9d7c0e991f55cf)
