CI: use shivammathur/setup-php for all PHP versions

Test 7.2 through 8.6 with a single shivammathur/setup-php matrix instead of the
docker-image based setup, which had no published php:8.6 image. 8.6 is built
from php-src master; fail-fast is disabled so a failure there does not cancel
the other versions.

The package.xml validation previously done in ci/test_inner.sh is kept as a
"pecl package" step. The now-unused ci/ docker scripts are removed.
