Summary:
The cppcoreguidelines-pro-bounds-pointer-arithmetic warns on all occassion where
pointer arithmetic is used, but does not check values where the pointer types
is deduced via ``auto``. This patch adjusts this behaviour and solved
PR36489.

With this, site specific lit configs can inject parameters into the
test scripts if they need site specific parameters.
Next up: enable check_clang_tidy to take a resource dir to enable
non-standard locations for builtin includes.

Summary:
This check flags all usage of pointer arithmetic, because it could lead
to an
invalid pointer.
Subtraction of two pointers is not flagged by this check.
Pointers should only refer to single objects, and pointer arithmetic is
fragile and easy to get wrong. array_view is a bounds-checked, safe type
for accessing arrays of data.
This rule is part of the "Bounds safety" profile of the C++ Core
Guidelines, see
