Switch to FixedArray implementation from abseil.

This PR changes the implementation of the current fixed array to the
abseil one, which has proper allocator support.
Some minor changes are made to make the fixed array implementation
self-contained (no dependent to abseil):
- No address sanitizer support (red zones, etc.)
- Remove of noexecpt specified for copy and move constructor.
- Remove of 'at' function as Ceres does not use exceptions.
- Use std::tuple instead of absl::CompressedTuple as it uses the  abseil
  utility header which includes a whole bunch of other headers.
