RFR: 8366671: Refactor Thread::SpinAcquire and Thread::SpinRelease [v3]

[Anton Artemov]

> Hi, 
> 
> please consider the following changes:
> 
> In this PR `Thread::SpinAcquire()` and `Thread::SpinRelease()` methods are refactored into a utility class `SpinCriticalSection`. The motivation is to make it easier for developers to use this lightweight synchronization mechanism in the codebase. The two aforementioned methods were used in JFR to create short critical sections with a helper class, but that was not the case for the object monitor code. 
> 
> Additionally, `SpinSingleSection` class is added, which allows to execute a payload code inside of a functor by only one thread. 
> 
> Tested in tiers 1 - 5.
