Changes in the compilers made it to where some includes would not be
included in some headers (see [this](https://gcc.gnu.org/gcc-13/porting_to.html#header-dep-changes) for more info) and one of those includes were `cstdint` / `stdint.h`. This commit brings the dependancy abseil-cpp to a commit that fixes that issue and included the relavent files in internel headers to fix the problem.
