Rebase

Use the template on the clang builds. Even though changes to functional tests only will be a false positive,
catching changes to /cmake are important. Functional test only changes are not super common, so we
can live with this tradeoff to reduce maintenance overhead and reduce false negatives.

Used a template where it makes sense. For the others, it doesn't make sense to run them when
only changes to the functional tests are made.

Let's try this. If this doesn't work well, we can disable caching all together.

Please remove the reference to overrides.css from the bcha page too

Move most of the includes to the footer. This looks better in some cases and puts it on more pages.

Apply my feedback from earlier

Ignore the failures. One of the build agents was having a network issue and failed multiple builds.

Similar to docindex, is it possible to add this to the page layout instead of the index and release pages directly?

Move the bulk of the implementation of FixedSeedsList into chainparams.cpp
