Introduce "analysis mode" flag to CLI

[3flex]

Expected Behavior

I can use rules that use type resolution without passing a classpath explicitly.

Current Behavior

Type resolution is only enabled when a classpath is passed in.

Context

detekt assumes that if no classpath is passed in, that type resolution & full analysis isn't possible. This isn't true though - we call configureJdkClasspathRoots unconditionally:
https://github.com/JetBrains/kotlin/blob/v1.9.23/compiler/cli/cli-base/src/org/jetbrains/kotlin/cli/jvm/config/JvmContentRoots.kt#L91-L103

It's possible to have a module that has no Kotlin dependencies at all, but depends on the JRE, or it might not have any dependencies at all. This is rare but detekt should properly handle this.

We could have a switch or flag to enable or disable full analysis mode so the intention is clear.
