[opentelemetry-cpp] unvendor absl polyfills (#30720) * [opentelemetry-cpp] unvendor absl polyfills By default opentelemetry vendors-in a copy of some Abseil polyfills (e.g. `absl::variant`). That makes it hard (I would claim nearly impossible) to use both the abseil and the opentelemetry-cpp ports at the same time, as both define `absl::variant` in some of their headers. It seems better to always use the `-DHAVE_ABSEIL=ON` CMake option and depend on the abseil port. Outside vcpkg it may be useful to use such vendored-in copies of the code, as that "simplifies" dependency management. In the context of vcpkg that is just wasteful. Simplified how to support `abseil[cxx17]` by removing some code in opentelemetry that forcibly downgraded the compiler to use C++11. Add a missing dependency for gRPC generated code. This code indirectly depends on Abseil too. * Opentelemetry is missing a find_dependency() when -DHAVE_ABSEIL=ON 2023-04-11 03:50:22 +08:00			`diff --git a/CMakeLists.txt b/CMakeLists.txt`
