55a8373ec3 Avoid sanitizer macros use Abseil's where necessary
Using C++17 means we can get rid of many `#ifdef`s by using `if constexpr`.
This way, we ensure that both branches compile and still retain zero runtime
overhead.

Note that open source builds of Sandboxed API do not ship with sanitizer
configurations yet. This will be added in follow-up changes.

dbaf95c724 Move utility code into sandboxed_api/util
This change should make it less confusing where utility code comes from.
Having it in two places made sense when we were debating whether to publish
Sandbox2 separately, but not any longer.

Follow-up changes will move `sandbox2/util.h` and rename the remaining
`sandbox2/util` folder.

2a9320dbac Update/simplify linker flags for testcases
- Bazel: Use "incompatible" flag to fix fully static linking. The flag will
  become the default in Bazel 4.0.
- Bazel: Deduplicate features into `FULLY_STATIC_FEATURES` variable
- CMake: Remove the testcase properties. `sapi::base` already sets
  `POSITION_INDEPENDENT_CODE`. Note that `-pie` is incompatible with `-static`
  and `-static-pie` requires GCC 8 and GLIBC 2.27.
