Hanif Koh f7794fc83d ci: cache compiled objects between runs ...

Every CI leg compiled the whole tree from scratch, 42 to 57 minutes of
each build job. Objects are now cached with ccache, one entry per leg
kept on the branch that built it: a push saves the cache and drops the
previous entry, a pull request restores main's and keeps nothing.

The precompiled header is turned off whenever the cache is on: Clang
stamps it with the build time, so every file including it missed. With
it off, a warm run hits 98.5 to 98.9 % of compiles and the compile steps
take 1 to 4 minutes; a cold run costs 25 to 60 % more than before, and a
change to a widely included header lands in between.
