Disable tidy checks in TidyGlobalNoChecks

* Save repeated strings in TidyFlags of build.ninja rules.
* Some of these checks were disabled to upgrade clang-tidy.
  They could later be moved to TidyDefaultGlobalChecks and
  TidyExternalVendorChecks if not breaking the build.
  Some projects can then enable those checks locally.

Test: WITH_TIDY=1 make; make tidy-soong_subset
