Fix issue with fixed Tooltip not working on nonAxisChart

[hhjeee]

Fixes #4720

This PR addresses an issue where the fixed option in the tooltip configuration for Pie/Donut charts was not working as expected. When tooltip: { fixed: { enabled: true } } option was set, the tooltip did not remain fixed in position.

Summary of Change

The problem was caused by the tooltip position being recalculated by thenonAxisChartsTooltips() function, which overwrote the fixed position of the tooltip. The issue was resolved by changing the order of function execution so that nonAxisChartsTooltips() runs first, followed by the drawFixedTooltipRect() function that fixes the tooltip position.
