Convert property id to string

[Jerrys-C]

Overview

Fix #258
This change restores the conversion of id to a string in the RegisterProperty function. The conversion was previously removed, but this update reintroduces it to prevent potential issues with property identifier handling

Details

Converting id to a string ensures consistent and reliable usage of property IDs within PropertiesTable and propertyData. This reversion addresses problems introduced by the previous removal of this conversion
