Add support for composite builds

[05nelsonm]

Closes #18

Now projects who utilize composite builds can create an extension function in their build-logic/build-support module such that they can configure containers multiple times

// :build-logic
// shared.gradle.kts
plugins {
    id("io.matthewnelson.kmp.configuration")
}

// :build-logic
// KmpConfigurationExtensionExt.kt
fun KmpConfigurationExtension.configureShared(
    action: Action<KmpConfigurationContainerDsl>
) {
    configure {
        // configuration for all projects that apply the "shared" plugin generated by shared.gradle.kts
        jvm {
            target { withJava() }

            kotlinJvmTarget = JavaVersion.VERSION_1_8
            compileSourceCompatibility = JavaVersion.VERSION_1_8
            compileTargetCompatibility = JavaVersion.VERSION_1_8
        }

        js()
//        wasm()
        wasmNativeAll()

        androidNativeAll()

        iosAll()
        macosAll()
        tvosAll()
        watchosAll()

        linuxAll()
        mingwAll()

        common {
            sourceSetTest {
                dependencies {
                    implementation(kotlin("test"))
                }
            }
        }

        action.execute(this)
    }
}

// :my-project
// build.gradle.kts
plugins {
    id("shared")
}

kmpConfiguration {
    configureShared {
        common {
            sourceSetMain {
                dependencies {
                    implementation(project(":my-other-project"))
                }
            }
        }
    }
}
