Nadav Har'El 5625624533 doc/dev: add document about analyzing build time

Add a document describing in detail how to use clang's "-ftime-trace"
option, and the ClangBuildAnalyzer tool, to find the source files,
header files and templates which slow down Scylla's build the most.

I've used this tool in the past to reduce Scylla build time - see
commits:

   fa7a302130 (reduced 6.5%)
   f84094320d (reduced 0.1%)
   6ebf32f4d7 (reduced 1%)
   d01e1a774b (reduced 4%)

I'm hoping that documenting how to use this tool will allow other
developers to suggest similar commits.

Scylla developer documentation

This folder contains developer-oriented documentation concerning the ScyllaDB codebase. We also have a wiki, which contains additional developer-oriented documentation. There is currently no clear definition of what goes where, so when looking for something be sure to check both.

Seastar documentation can be found here.

User documentation can be found on docs.scylladb.com

For information on how to build Scylla and how to contribute visit HACKING.md and CONTRIBUTING.md.
