Add extended testing support with testing:extended label

Add support for triggering extended test suite when testing:extended label
is added to a PR. Five additional test jobs run serially after the standard
build, each with different test options: --parallel, --optimization=-O3,
--check-type check-read1, --check-type check-readmore, and a HIP board test
with --runtestflags=--target_board=hip --tests gdb.base/break.exp.

Extended test jobs use `if: success() || failure()` to ensure all tests run
even if one fails, while still showing which tests failed in the UI. This
provides complete test coverage on demand without slowing down the standard
CI pipeline.
