[GR-27173] Automatic conditional configuration generation.

[graalvmbot]

This PR implements automatic conditional config generation in the agent.

Usage

To enable this feature, pass the experimental-conditional-configuration=<package-prefixes> option to the native-image agent. The <package-prefixes> parameter is a comma separated list of packages - classes from these packages will be used to generate conditions.

Only while using this mode, a special agent option class-name-filter=<regex-list> is available. This option accepts a comma separated list of regex patterns - classes in both the configuration condition and, where applicable, the configuration itself will be removed from the final configuration.

Implementation

This implementation leans on the configuration with origins tracing to generate a call graph where origins of each configuration entry are known. Using this information, the config is generated in the following steps:

1. For each unique method in the call graph, generate a list of nodes, one node for each call of that method. Assign an initial configuration set to that node, or an empty set if no configuration was traced in that call.
2. For each list of nodes, iterate and find the common configuration between the nodes in that list.
3. For each node in said list, keep the common configuration and propagate the node specific configuration to the caller node.
4. Repeat steps 2. and 3. while there are still changes in any of the node lists.
