Bug description:
  As done for gcc-7 and gcc-8 in 18.04 LTS in LP: #1848319, I'd like to
  update the gcc-9 and gcc-10 packages in focal to the final 10.2.0
  release.

   - gcc-10, update to the gcc-10.2.0 release
   - gcc-9, update to the gcc-9 release branch to the time
     of the gcc-10 release.
   - corresponding gcc-cross packages

  The package builds are prepared in
  https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa/+packages

  [Impact]
  Provide an upstream release for GCC 10.2, and an update for GCC 9 to the 9.3 branch

  [Regression Potential]
  There is regression potential, however with a test rebuild of the main portion of the archive no regressions were found.

  [Test Case]
  No regressions in the GCC test suite, and no regressions in the test
  rebuild of the main component of the archive (all architectures)

  As a test, a complete archive rebuild was performed, and no
  regressions were found with this new package. The archive rebuild also
  contained updated versions of gcc-9, gcc-10, python3.8, and python3
  -stdlib-extensions. The GCC and Python packages should not infer with
  each other.

  [Validation]
  Analyze the build logs for regressions.
  For the cross builds, just make sure that the packages build using
  the updated sources.

  Summary of the test rebuilds:
  https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200810-focal-focal.html
  https://people.canonical.com/~doko/ftbfs-report/test-rebuild-20200810-focal-gcc-focal.html

  The first one is a reference build, the second one the test rebuild
  with the updated components.

  There are no additional regressions except for pyxdg, which is
  unrelated to the GCC update, and which was fixed by a separate SRU.
  Note that the riscv64 builds are purely informational, and are not
  checked for any regressions.
