docker: bump up to clang {18,19} and gcc {13,14}

since we only support the latest two major releases of compilers.
at the moment of writing, Clang just released v19, and the latest
major release of GCC is v14.

so we should install them respectively.

because ubuntu mantis is already EOF. see
https://wiki.ubuntu.com/Releases. and it does not include the
latest GCC and Clang packages. we need to bump up the base image
from ubuntu:mantis to ubuntu:orcular despite that orcular is not
an LTS release. we should use new ubuntu LTS release once it's out.
