[Scene] Add SceneStringNames::pressed

[AThousandShips]

This is a very common name used across the codebase, unsure what the practical impact is but since there's about 700 uses of these I think it's a pretty good candidate to add, will check for other cases that are very common as well

Also considering:

• FlatButton 228 cases
• font_color 196 cases
• Tree 191 cases
• Label 165 cases
• id_pressed 161 cases [Scene] Add SceneStringNames::id_pressed #91949
• panel 145 cases [Scene] Add SceneStringNames::panel #91950
• font 132 cases
• item_selected 131 cases
• confirmed 124 cases
• font_size 121 cases
• text_changed 117 cases
• value_changed 115 cases
• emit_signal 78 cases (for CoreStringNames)
• toggled 72 cases
• normal 72 cases (using already existing CoreStringNames::normal) Use CoreStringNames::normal in more places #91953

Looks ok.

It might be interesting to do some simple benchmark here. This will obviously reduce binary size (all similar changes do), but it can also minimally improve editor startup time.

Looks good to me.

Another one to tackle in the same category would be toggled. Not as frequent, but still:

$ rg 'connect.*"toggled"' | wc -l
71
