[jdk17u-dev] RFR: 8272654: Mark word accesses should not use Access API

[Aleksey Shipilev]

Clean backport to sync up 17u, 21u and tip versions of the `markWord` code. This simplifies maintenance and further backports.

Additional testing:
 - [x] Eyeballing object code for affected methods, they are exactly the same on AArch64
 - [ ] Linux x86_64 fastdebug `tier1 tier2 tier3`
 - [ ] Linux AArch64 fastdebug `tier1 tier2 tier3`
