Add some missing barriers when dealing with global caches (mono/mono#18032)

* Add some missing barriers when dealing with global caches
accessed from multiple threads without locks.

This is based on earlier PR https://github.com/mono/mono/pull/17849.

Read-side barriers are removed.
  More analysis is needed to determine if they are needed (which pointer
  read vs. written).
Write-side barriers are compiler barrier + store-release instead of full barrier.

Note all candidates are converted to new form yet.

Cases that do motivate read-wide barriers are skipped.
e.g.
`mono_arch_start_dyn_call`
`get_agent_domain_info`
`init_jit_info_dbg_attrs`

* PR: Remove 'Try one more time..'
