Make BaselineModuleJvmArgs Configuration-Cache friendly

[kelvinou01]

Before this PR

We are trying to get our repositories to run classes and test with the Configuration Cache. Currently, BaselineModuleJvmArgs has these CC issues:

- [error] cannot serialize object of type `org.gradle.api.internal.project.DefaultProject`, a subtype of `org.gradle.api.Project`, as these are not supported with the configuration cache.
    - field `val$project` of `com.palantir.baseline.plugins.BaselineModuleJvmArgs$1`
        - bean of type `com.palantir.baseline.plugins.BaselineModuleJvmArgs$1`
            - field `action` of `org.gradle.api.internal.AbstractTask$TaskActionWrapper`
                - bean of type `org.gradle.api.internal.AbstractTask$TaskActionWrapper`
                    - field `actions` of `org.gradle.api.tasks.javadoc.Javadoc`
                        - task `:gradle-guide-error-prone:javadoc` of type `org.gradle.api.tasks.javadoc.Javadoc`
- [error] cannot serialize object of type `org.gradle.api.internal.tasks.DefaultSourceSet`, a subtype of `org.gradle.api.tasks.SourceSet`, as these are not supported with the configuration cache.
    - field `val$sourceSet` of `com.palantir.baseline.plugins.BaselineModuleJvmArgs$1`
        - bean of type `com.palantir.baseline.plugins.BaselineModuleJvmArgs$1`
            - field `action` of `org.gradle.api.internal.AbstractTask$TaskActionWrapper`
                - bean of type `org.gradle.api.internal.AbstractTask$TaskActionWrapper`
                    - field `actions` of `org.gradle.api.tasks.javadoc.Javadoc`
                        - task `:gradle-guide-error-prone:javadoc` of type `org.gradle.api.tasks.javadoc.Javadoc`

After this PR

Instead of capturing Gradle domain objects (SourceSets and Projects) in tasks, use providers as inputs.

Possible downsides?

[FinlayRJW]

can we get a test case for this?

[FinlayRJW]

Rather than wrapping this in a provider can we just make collectClasspathInfoForSourceSet return a provider - something like this should work I think:

        return classpath.getElements().map(fileSystemLocations -> fileSystemLocations.stream()
                .map(FileSystemLocation::getAsFile)
                .map(file -> { ... }))
