Subject: chore(3p/abseil_cpp): unvendor abseil_cpp

we weren't actually using these sources anymore, okay?

-//
-// `absl::BitGenRef` is a type-erasing class that provides a generator-agnostic
-// non-owning "reference" interface for use in place of any specific uniform
-// random bit generator (URBG). This class may be used for both Abseil
-// (e.g. `absl::BitGen`, `absl::InsecureBitGen`) and Standard library (e.g
-// `std::mt19937`, `std::minstd_rand`) bit generators.
-//
-// Like other reference classes, `absl::BitGenRef` does not own the
-// underlying bit generator, and the underlying instance must outlive the
-// `absl::BitGenRef`.
-//
-// `absl::BitGenRef` is particularly useful when used with an
-// `absl::MockingBitGen` to test specific paths in functions which use random
-// values.
-//
-// Example:
-//    void TakesBitGenRef(absl::BitGenRef gen) {
-//      int x = absl::Uniform<int>(gen, 0, 1000);
-//    }
-//
-class BitGenRef {
-  // SFINAE to detect whether the URBG type includes a member matching
-  // bool InvokeMock(base_internal::FastTypeIdType, void*, void*).
-  //
-  // These live inside BitGenRef so that they have friend access
-  // to MockingBitGen. (see similar methods in DistributionCaller).
