fix: Update Tests

[jtriley-eth]

Description

Remove tests from impl blocks, dedupe test names.

Additional Context

Tests now fail for msm on Secp256r1, MNT6_753, MNT4_753, and Secp384r1 curves. I'm unsure what msm means, but the error originates in the Curve::evaluate_linear_expression method and fails in __compute_quadratic_expression_with_borrow_flags from the noir-bignum library, specifically:

assert(remainder == [0; N]);
