Refactor code to never do casts

[SilasKenneth]

Given the code

if ($parseNode->getBooleanValue() !== null) {
    $result->setBoolean($parseNode->getBooleanValue());
} else if ($parseNode->getFloatValue() !== null) {
    $result->setDouble($parseNode->getFloatValue());
} else if ($parseNode->getIntegerValue() !== null) {
    $result->setInteger($parseNode->getIntegerValue());
} else if ($parseNode->getStringValue() !== null) {
    $result->setString($parseNode->getStringValue());
}

With the current ParseNode implementation, the code will always never go to other branches of the if (unless getBooleanValue() returns null) since anything can be cast to boolean making the first branch of the if always true.

This work is part of
microsoft/kiota#2827

The merge-base changed after approval.
