[lworld] RFR: 8367935: [lworld] Rename ACC_STRICT in the JVM according to strict fields JEP [v2]

[Matias Saavedra Silva]

> Strict initialization is now indicated with the access flag `ACC_STRICT_INIT` in the JVMS and the VM implementation should follow. `ACC_STRICT` is currently used as a method modifier for strict floating-point semantics so this refactor will help to make both modifiers distinct. VM and Java code has to be updated to use the correct modifier. Verified with tier x-y tests.

Matias Saavedra Silva has updated the pull request incrementally with one additional commit since the last revision:

  Remove strict_init from Modifier
