[Kbn grid layout] Use max_value instead of infinity

[ThomThomson]

Summary

Fixes #243364 by using Number.MAX_VALUE instead of Infinity for the default maximum height of a panel.

Explanation

The tab crash was caused by the dragged panel on the Dashboard attempting to resize their height to NaN. The NaN came from the getRowCountInPixels function when attempting to calculate max pixel height of the panel to calculate the bottom of the preview rect:

Working case (main)

const rowCount = Infinity;
const rowHeight = 30;
const gutterSize = 8;

// ( Infinity * 30 = Infinity) + ( Infinity * 8 = Infinity  )  = Infinity
return rowCount * rowHeight + (rowCount - 1) * gutterSize

Broken case (main)

const rowCount = Infinity;
const rowHeight = 30;
const gutterSize = 0;

// ( Infinity * 30 = Infinity) + ( Infinity * 0 = NaN  )  = NaN
return rowCount * rowHeight + (rowCount - 1) * gutterSize

Fixed case (This PR)

const rowCount = MAX_VALUE;
const rowHeight = 30;
const gutterSize = 0;

// ( MAX_VALUE * 30 = Infinity) + ( MAX_VALUE * 0 = 0  )  = Infinity
return rowCount * rowHeight + (rowCount - 1) * gutterSize

LGTM! I tested this and it seemed to resolve my issues with freezing tabs.
