The automatic wire tool was not working in the gridless mode because the
grid snapping on/off logic present in `EE_GRID_HELPER`, based on the
value of `m_enableGrid`, was not taking into account that another check,
but for the global KiCad setting, would be performed in the `Align()`
method, which is inherited from `GRID_HELPER`.
I've modified all tests of `m_enableGrid` value to also take the global
setting into account, and moved checks for it to `Align()` method, as
it's more consistent this way.
I've also removed an override of the `Align()` method in the
`PCB_GRID_HELPER` class, as it was made redundant by my changes.

In particular, allow grid positions to override line snapping if
they're a better match (and do this independently on x and y axes).
We already allow a nearer anchor to override, but that should be
based on a cartesian distance rather than independent axes.

The snap range needs tuning to preference and monitor resolution. This
shifts the default range down for users until the customization bits are
implemented.
You can now enable and disable snap to grid when drawing/editing across
all apps. You can also tie snap to grid to the visibility of the grid
to allow rapid enable/disable via grid display.
