[PW_SID:791822] ecc: fix incorrect derivation of compressed points

[IWDTestBot]

The logic was inversed here and was performing a subtraction if:

• Y was even and type == BIT0
• Y was odd and type == BIT1

This is not correct according to the ANSI spec. IWD relied on this
API but had matching incorrect logic so things "worked" up until
a compressed point needed to be parsed from an source that
explicitly specified the type (e.g. an ASN1 DER in DPP). All other
uses (PWD/SAE) the point type was only used to force a subtraction
so since both locations used the incorrect logic the points would
compute correctly.
