Move all CustomData correction logic used on Edge/Vert Slide to `transform_convert_mesh.c`

And apply changes to mirror elements

Rename `TransDataMirror` members and use bitfield for sign

Cleanup: Use more descriptive variable names

EditMesh support mirror on all axes

Part of T68930

This patch adds two more mirror options that can be enabled simultaneously: Mirror Y and Z.

Since different transformation options use their own mirroring code (eg edge / vert slide and proportional editing), this patch proposes a generic solution that can be applied to any transformation.

The idea is to create a new array type that points to the location of each reference element with the mirror element location.

This reduces the amount of `TransData` that is already overkill.
