Adds a bootstrap method to the BootstrapMethods attribute of this symbol table. Does nothing if
the BootstrapMethods already contains a similar bootstrap method (more precisely, reverts the
content of {@link #bootstrapMethods} to remove the last, duplicate bootstrap method).

@param offset the offset of the last bootstrap method in {@link #bootstrapMethods}, in bytes.
@param length the length of this bootstrap method in {@link #bootstrapMethods}, in bytes.
@param hashCode the hash code of this bootstrap method.
@return a new or already existing Symbol with the given value.
