Introduce "-api-version" CLI option
The `@SinceKotlin("X.Y.Z")` annotation now hides a particular declaration from
resolution when the API version specified by the `-api-version` option is
_less_ than X.Y.Z. The comparison is performed as for versions in Maven:
MavenComparableVersion is in fact a copy of
org.apache.maven.artifact.versioning.ComparableVersion.
Also support "!API_VERSION" directive in diagnostic tests

* <li>strings are checked for well-known qualifiers and the qualifier ordering is used for version ordering.
|

* Well-known qualifiers (case insensitive) are:<ul>

|

* <li><code>beta</code> or <code>b</code></li>

|

* Unknown qualifiers are considered after known qualifiers, with lexical order (always case insensitive),

* </li>
|
