FlameGraph: Add option to align text left or right

Also changes some css to align a bit with the button in graph panel.

There is a bit of special behaviour:

• if the label (without the value part) fits in the node the alignment has no effect
• if aligned to the right it does not show the value part as main point imho to see the function name in this case

Known issues:

• in small window size or panel size in dashboard the buttons stack in ugly way
• there is a weird margin in the buttons with icons so the align icons seem off center but this needs to be fixed in the UI component Grafana/ui: Fix margin in RadioButtonGroup option when only icon is present #68899

Sweet!

One nit, the icon buttons would look even better if either the right margin was removed or the icons were center aligned in the buttons.

@joey-grafana yeah I mention it in the description, created a separate PR for that.
