RFR: 8303930: Fix ConstantUtils.skipOverFieldSignature void case return value [v4]

[Chen Liang]

> This typo doesn't allow creation of malformed ClassDesc or MethodTypeDesc, but it produces an erroneous exception on certain inputs. Running `java.lang.constant.MethodTypeDesc.ofDescriptor("(IIIII[[[V)I")` in Jshell 19.0.2 throws StringIndexOutOfBoundsException, and throws IllegalArgumentException in the Jshell for this patch.
