Previously we used org.glassfish:jakarta.el as our default EL
implementation. Since adopting it we have learned that it can be
significantly slower than Apache Tomcat's EL implementation in some
scenarios. This commit switches to using
org.apache.tomcat.embed:tomcat-embed-el by default instead of the
Glassfish implementation.

Update `LoggingSystemProperties` so that system environment properties
are also applied to the `LoggerContext`. This is required when multiple
applications are deployed to the same Servlet container. In such setups
there's only a single JVM and the System Environment can be changed
when multiple applications start at the same time.
