Apply the CLANGFORMAT linter to fbcode/tools/**.

Summary:
Context: FBCode doesn't enable CLANGFORMAT linter over the entire repo because too many files currently don't conform to it. This is an attempt to migrate folder paths to use CLANGFORMAT conventions.

Post: https://fb.workplace.com/groups/fbcode.fyi/permalink/4213072448728524/
Doc: https://fburl.com/clangformat-for-fbcode

Actions: Please check the formatting recommendations and accept if they seem ok, or reply if there is a reason for concern. NOLINT or NOLINTNEXTLINE have been added at places where linter errors were found. Please fix these when its convenient.

Command run:
```
arc lint --take CLANGFORMAT -a --paths-cmd 'hg files tools/**'
```
