RFR: 8332505: JEP 457: ClassRemapper forgets to remap bootstrap method references

[Adam Sotona]

Class-File API `ClassRemapper` component suppose to remap all classes referenced in a class file.
Actual implementation missed remapping of bootstrap methods referenced from `invokedynamic` instructions.
This patch fixes the remapping and adds relevant test.

Please review.

Thanks,
Adam
