Use connect-and-lease when using daemon in JPS & Gradle

Relates to KT-15562 "Service is dying".

This commit includes multiple changes:
 1. JPS & Gradle daemon clients are refactored to use `connectAndLease` from `KotlinCompilerClient`.
 `connectAndLease` was introduced in previous commits
 2. `withKotlin` was removed because `connectAndLease` already covers retrying on connection error
 3. Gradle flag files creation is changed:
   * client-alive flag file lives as long as Gradle instance lives,
   * session-alive flag file lives until the end of a build.
