This makes all of the clangd tests work with the internal shell.
Modifications needed for each test are as follows:
1. system-include-extractor.test was using variable expansion which is
   not supported in the internal shell. This patch rewrites it to use
   the readfile mechanism along with python. This isn't super pretty but
   is readily understandable and there are only two tests across the
   monorepo that use this construction, so making it prettier is hard to
   justify.
2. include-cleaner-batch-fix.test - Was using $'' construction to create
   new lines in a string. Simply replace it with multiple echo commands
   to be canonical with the rest of the repository.
3. index-tools.test - Just add IndexBenchmark to the clangd test
   depends, so the test now just works unconditionally. This should
   significantly increase test coverage at little cost.
