RFR: 8292302: Windows GetLastError value overwritten by ThreadLocalStorage::thread [v3]

[Kevin Walls]

> This is an MR which partially reverts JDK-8289091 such that JavaThread::threadObj() does not call Thread::current().
> 
> A JVMTI operation could call threadObj() and clear the Windows GetLastError value.
> 
> Partial, because I haven't reverted changes in JavaThread::print_on_error(), they aren't connected to the problems seen.
