Make moxyPresenter property delegate inline

[alaershov]

Apparently our moxyPresenter property delegate can be optimized:

Property delegation to noinline function(s) causes (reflective) KProperty creation which slows down initialization and should be avoided in applications which should start up fast.

The fix is either to delegate to inline functions (optimized since Kotlin 1.3.60) or to delegate manually.

See these issues in Kotlin YouTrack:

• Suboptimal compilation of lazy delegated properties with inline getValue
• More flexible delegated property convention
• Support Delegates without KProperty
