Some editor fields don't accept comma as a decimal separator

Issue description

Most numerical fields in editor like inspector properties and settings accept comma as input (eg. 5,5 gets parsed to 5.5). However, there's some inconsistency in this support. Color picker doesn't support this and also Input Map's deadzone fields.

Steps to reproduce

Open any color picker in inspector or Input Map settings, try to input value like 0,5 in it.

Minimal reproduction project

Any project

Accepting commas as decimal separator was special-cased in EditorSpinSlider, but not SpinBox: #42376
This is because valid Expressions may contain commas, such as pow(2, 16) = 65536. We could also break support for those expressions in SpinBox to make commas work as a decimal separator there – I'm not sure how many people rely on expressions with commas in SpinBox in practice.

Like ColorPicker, the input map editor's deadzones also use bare SpinBoxes, not EditorSpinSliders.

If we want to do a more elaborate workaround, we could replace , with . only if the expression doesn't contain any parentheses. This way, you can still use pow() and comma separators will keep working in simple math operations.

Nice to hear that there's some reasoning behind this. Your suggestion sounds like win-win. Using keyboard layout (finnish here) where numpad has comma, not period, I always end up filling these field twice - first with comma, only then notice the mistake. I'm infinitely grateful that inspector parses commas also 👍
