[clsi] prepare for clsi-cache survey (#29274)

* [clsi] add stats and timings to compile response from clsi-cache

* [clsi] set downloadedFromCache when previously downloaded for synctex

Assumption: every compile will emit an output.log. When the output.log
is missing, but the output.synctex.gz exists, it must have been
downloaded from the cache.
