Generated codes like cpp code from *.ll for *.yy files always run
clang-tidy, when generated code has warning, where is no way to fix it.
So, disable clang-tidy for generated code.

Test: go test android/soong/cc

* A follow up CL will set const NoWarningsAsErrorsInTidyFlags
and make it an error to use -warnings-as-errors in tidy_flags.
* Append TidyGlobalNoChecks after local tidy_checks to disable some checks.
* Append TidyGlobalNoErrorChecks after local tidy_checks_as_errors
(-warnings-as-errors) to allow some warnings globally.
* Move bugprone-signed-char-misuse and bugprone-branch-clone to
globalNoErrorCheckList so we can find and fix some of those warnings.

* 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.

* Also remove the undocumented complicated
experiment to overwrite local warnings-as-errors.

* If a module defines tidy_checks with "-*",
pass only "-*" and checks after it to clang-tidy.

* A new ALLOW_LOCAL_TIDY_TRUE variable, default is false.
* If it is 0/false, local "tidy:true" is ignored.
* If it is 1/true, local "tidy:true" is honored as it is now.
