[lworld] RFR: 8253511: [lworld] ClassFileParser does not handle field type mismatch

[Frederic Parain]

Please review this change with replaces an assert with the throwing of an IncompatibleClassChangeError when a
pre-loaded class is not an inline type. This case was correctly handled for static fields, but not for non-static
fields.

Tested with Mach5, tiers 1 to 3.

Thank you,

Fred
