Trying to support changing member accessibility

[thaystg]

Fixes #108097

[thaystg]

@lambdageek if this is what you were suggesting I will create a test case on wasm debugger tests after your review.

@lambdageek it also works if I don't call mono_field_resolve_type

@lambdageek It also works if I completely remove this else.

@thaystg in your test was the field previously used? if field->type != NULL then mono_field_resolve_type should overwrite it and include the new visibility attributes.

Something like the f2 function in this example #108097 (comment) - should see the new visibility. So if you're changing public->private then f1 that already ran before the update will keep working, but f2 created after the update should throw a MemberAccessException

Let's not do it like this. the add_member_XXX variables are there because the ADD functions all come paired with another row with a DEFAULT function - it's kind of a hack to make sure we process them together. we don't need it for rows that are self-contained.

Just move the assert in the MONO_TABLE_FIELD case into the is_addition branch:

  if (is_addition) {
     g_assert (add_member_typedef);
    // the rest is all the same
  } else {
     // just use log_token instead of add_member_typedef
 }

@thaystg FYI, from Tomas:

All members and types.

We also need to support changing visibility for methods/properties/events/nested types
