Add the ability to define the width of the popover in ComboBox/AutoComplete

[dannify]

Provide a general summary of the feature here

Pickers currently allow for a custom width using the menuWidth prop see docs

We want to allow this option in ComboBox and AutoComplete. It should always default to the width of the input, as it does now, however if the prop menuWidth is set, use that instead.

Note: menuWidth needs to be >= width of the input. If the prop is < the input, default to the min-width and ignore the prop.

🤔 Expected Behavior?

Allow the popover width to be customizable.

😯 Current Behavior

No option to control this

💁 Possible Solution

Similar to

react-spectrum/packages/@react-spectrum/picker/src/Picker.tsx

Lines 137 to 140 in 5dac45c

	let style = {
	width: menuWidth ? dimensionValue(menuWidth) : width,
	minWidth: isQuiet ? `calc(${buttonWidth}px + calc(2 * var(--spectrum-dropdown-quiet-offset)))` : buttonWidth
	};

🔦 Context

Use case of combobox and autocomplete where the content of the options needs more room to display. Truncation might not always be the right answer.

@dannify Hi! I want to take a stab at this.

By the way, just to make sure I understood everything correctly, by AutoComplete you mean SearchAutocomplete under the pickers category in React Spectrum, right? I'm asking this because I don't see it under the pickers category in current docs, but I DO see it (tagged as alpha) when I run yarn start:docs on main branch.
