support kotlin multiplatform modules

[0xera]

closes #13

[MinhNguyen-nvm]

The issue is that a KMP module could be both a jvmJar and an Android module at the same time. (Provide a jar file & aar file)
It's broken the current SizerVariant; let me update the API to support this feature.

[MinhNguyen-nvm]

I already work on this issue, let me share the MR later

[0xera]

The KMP module requires the android-library plugin to be included if an Android target is specified. Therefore, the Android AppSizeVariant already includes all sources when building AAR

[MinhNguyen-nvm]

Oh. interesting, the AAR file contains the module's JVM classes as well
Earlier, I saw the kmp-module has jar & aar files simultaneously if we have both JVM & android config. I did not check the binary content.

Then it should work. Let me review the MR properly later

[MinhNguyen-nvm]

internal const val KMP_JAR_TASK = "jvmJar"
internal const val KMP_RUNTIME_CONFIGURATION = "jvmRuntimeClasspath"

Let's have a separate class for KMP.

internal class KmpSizerVariant(
    private val project: Project
) : SizerVariant {
    override val binaryOutPut: File
        get() {
            val jarTask = project.tasks.findByName(KMP_JAR_TASK) as Jar
            return jarTask.archiveFile.get().asFile
        }

    override val runtimeConfiguration: Configuration by lazy {
        project.configurations.first {
            it.name.equals(KMP_RUNTIME_CONFIGURATION, true)
        }
    }

    override val buildType: String
        get() = ""
    override val buildFlavor: String
        get() = ""
}

Can merge with the other two

            project.isKotlinJvm || project.isJava || project.isKotlinMultiplatform -> {
                return JavaModuleDependency(
                    name = project.pathTrimColon,
                    pathToArtifact = matchVariant.binaryOutPut.path
                )
            }

[MinhNguyen-nvm]

Could you help to merge

internal const val KMP_JAR_TASK = "jvmJar"
...
            project.isKotlinMultiplatform -> {
                task.dependsOn(project.tasks.named(KMP_JAR_TASK))
            }

            project.isKotlinJvm || project.isJava -> {
                task.dependsOn(project.tasks.named(JavaPlugin.JAR_TASK_NAME))
            }
