[Feature] Support future function call with "_xlfn." prefix in formula for compatibility

[catssay]

Initial checklist

• Is this really a problem?
• I have searched the Github Issues for similar issues, but did not find anything.

Problem

Univer does not correctly recognize the "_xlfn." prefix in formulas, even when the corresponding function exists in Univer. For example, in the formula "_xlfn.STDEV.S(Returns!C3:C253)", the function "STDEV.S" is already available in Univer. The "_xlfn." prefix indicates that the formula originates from a newer version of Excel and that the function may not exist in the current version. However, since the function is present in Univer, the prefix should be handled appropriately.

This is a relatively low-priority task with no plans for implementation in the short term. We will add it to the backlog.

Sure.

If anyone encounters this issue, they can register functions with the same name in unver using the prefix "_XLFN" (ensure it's uppercase) for compatibility.

For example, to register the function "_XLFN.STDEV.S", set its function body to use StdevS, which is available in the engine-formula package:

Using UniverSheetsCorePreset

presets: [
    UniverSheetsCorePreset({
        formula: {
            function: [[StdevS, "_XLFN.STDEV.S"]],
        }
    })
]

Using UniverFormulaEnginePlugin directly

univer.registerPlugin(UniverFormulaEnginePlugin, {
    function: [[StdevS, "_XLFN.STDEV.S"]]
})
