[lworld] RFR: 8349945: Implement strict static fields (proposed JVM feature) [v2]

[Matias Saavedra Silva]

> This patch enables and implements verification for fields with the ACC_STATIC and ACC_STRICT modifiers. To enforce strictness on static fields, the reads and writes on the field are tracked dynamically to ensure that the field is written before being read and written to before.
