1200a46e49 feat(compiler): Add HLFHE pass selecting maximum MANP and encrypted integer width
This pass calculates the squared Minimal Arithmetic Noise Padding
(MANP) for each operation using the MANP pass and extracts the maximum
(non-squared) Minimal Arithmetic Noise Padding and the maximum
ecrypted integer width from.

ed762942c1 feat(compiler): Add pass for Minimal Arithmetic Noise Padding
This pass calculates the squared Minimal Arithmetic Noise Padding
(MANP) for each operation of a function and stores the result in an
integer attribute named "sqMANP". This metric is identical to the
squared 2-norm of the constant vector of an equivalent dot product
between a vector of encrypted integers resulting directly from an
encryption and a vector of plaintext constants.

The pass supports the following operations:

 - HLFHE.dot_eint_int
 - HLFHE.zero
 - HLFHE.add_eint_int
 - HLFHE.add_eint
 - HLFHE.sub_int_eint
 - HLFHE.mul_eint_int
 - HLFHE.apply_lookup_table

If any other operation is encountered, the pass conservatively
fails. The pass further makes the optimistic assumption that all
values passed to a function are either the direct result of an
encryption of a noise-refreshing operation.
