  -----------
  [builtins] Mark `int_lib.h` builtins as `static` (#69305)

Mark the following symbols as `static` to prevent duplicate definitions:

`__builtin_ctz`
`__builtin_clz`
`__builtin_clzll`
`__builtin_sadd_overflow`

>Without these then all of these functions show up in all object files
which include int_lib.h on Windows. This'll help prevent duplicate
symbols by ensuring they're not exported.
