fix(explore): Fix generic X-axis time grain disappearing

[codyml]

SUMMARY

In #21315, I refactored shared controls so feature flag checking for drag and drop was done in React render instead on module load. As part of that, I modified the config object's options property to be an array instead of an object for some DnD shared controls, because non-DnD versions expected an array and I wanted to merge DnD and non-DnD config objects. But, I missed a place where a visibility function expected an object, causing the Time Grain control to not appear when GENERIC_CHART_AXES is enabled. This PR fixes that issue.

After the option is changed from an Object to an Array, we have to loop through the entire Array. This is an O(n) operation.

	if (isPhysicalColumn(xAxisValue)) {
	return !!xAxis?.options?.[xAxisValue]?.is_dttm;
	if (isPhysicalColumn(xAxisValue) && Array.isArray(xAxis?.options)) {
	for (let i = 0; i < xAxis.options.length; i += 1) {
	if (xAxis.options[i].column_name === xAxisValue) {
	return !!xAxis.options[i].is_dttm;
	}
	}
	}
	if (isPhysicalColumn(xAxisValue)) {
	return !!(xAxis?.options ?? []).find(col => col.column_name === xAxisValue)?.is_dttm;
	}

Merged this PR first because Time Grain blocked testing others' fixes. @codyml thanks for the quick fixing!
