Remove TLSv1.1 and TLSv1 from MODERN_TLS. Change COMPATIBLE_TLS to support all TLS versions.

##### RESTRICTED_TLS versions

* TLSv1.3
* TLSv1.2

##### MODERN_TLS versions

* TLSv1.3
* TLSv1.2
* **REMOVED:** ~~TLSv1.1~~
* **REMOVED:** ~~TLSv1~~

##### COMPATIBLE_TLS versions

* **NEW:** TLSv1.3
* **NEW:** TLSv1.2
* **NEW:** TLSv1.1
* TLSv1

 *  **`RequestBody.contentLength()` now throws `IOException`.**
    This is a source-incompatible change. If you have code that calls
    `RequestBody.contentLength()`, your compile will break with this
    update. The change is binary-compatible, however: code compiled
    for OkHttp 2.0 and 2.1 will continue to work with this update.

 *  **`COMPATIBLE_TLS` no longer supports SSLv3.** In response to the

  return try {
    val (major, minor, _) = ideaVersionString.split(".", limit = 3)
    KotlinVersion(major.toInt(), minor.toInt()) < KotlinVersion(2023, 2)
  } catch (e: Exception) {
    false // Unknown version, presumably compatible.
  }

By default, OkHttp will attempt a `MODERN_TLS` connection.  However by configuring the client connectionSpecs you can allow a fall back to `COMPATIBLE_TLS` connection if the modern configuration fails.

```java
OkHttpClient client = new OkHttpClient.Builder()
    .connectionSpecs(Arrays.asList(ConnectionSpec.MODERN_TLS, ConnectionSpec.COMPATIBLE_TLS))
    .build();
```
