[GR-75824] Runtime-configurable assertion support

[graalvmbot]

This PR adds support to Native Image for these runtime assertions options:

    -ea[:<packagename>...|:<classname>]
    -enableassertions[:<packagename>...|:<classname>]
                  enable assertions with specified granularity
    -da[:<packagename>...|:<classname>]
    -disableassertions[:<packagename>...|:<classname>]
                  disable assertions with specified granularity
    -esa | -enablesystemassertions
                  enable system assertions
    -dsa | -disablesystemassertions
                  disable system assertions

This applies to all runtime loaded classes. If -H:+StrictRuntimeJavaOptions is specified, it also applies to runtime-initialized image classes.

The assertion status of build-time initialized classes is solely governed by the native image assertions options (same name and format as the above runtime assertion options). The assertion status of these classes is fixed at build-time. If StrictRuntimeJavaOptions is enabled, it also applies to runtime-initialized image classes.
