  -----------
  [clangd] Track time spent in filesystem ops during preamble builds

In some deployments, for example when running on FUSE or using some
network-based VFS implementation, the filesystem operations might add up
to a significant fraction of preamble build time. This change allows us
to track time spent in FS operations to better understand the problem.
