[native] Drop deprecated Kotlin/Native targets (3/8)

This commit inlines some helper-APIs that became redundant after
dropping deprecated targets.

Full list:
- 'threadsAreAllowed' is always 'true' now
- 'indirectBranchesAreAllowed' is always 'true' now
- 'supportsThreads' is always 'true' now
- 'isMips' is always 'false' now
- 'tlsMode' is always 'LLVMGeneralDynamicTLSModel' now
- 'getBoxRange' is always equal to 'cache.defaultRange' now
-  `targetHasAddressDependency` is always true now, so memory order
   is always LLVMAtomicOrderingMonotonic now
