There are several places where a new (internal) complex constant is allocated via new(Mpcplx) rather than newMpcmplx(). The problem with using new() is that the Mpcplx data structure's Real and Imag components don't get initialized with an Mpflt of the correct precision (they have precision 0, which may be adjusted later). In all cases but one, the components of those complex constants are set using a Set operation which "inherits" the correct precision from the value that is being set. But when creating a complex value for an imaginary literal, the imaginary component is set via SetString which assumes 64bits of precision by default. As a result, the internal representation of 0.01i and complex(0, 0.01) was not correct. Replaced all used of new(Mpcplx) with newMpcmplx() and added a new test. Fixes #30243.
