refactor(lib): tidy doom-log output

This commit reduces the debug log noise, makes it easier to
read/parse/search, and soft-introduces a convention for doom-log
messages, where they are prefixed with a unique identifier loosely named
after it's running context or calling function.

I haven't enforced it everywhere doom-log is used yet, but this is a
start.
