Fix style of all enum classes in editor

Fix capitalization of `EAxisLock` literals (e.g. `EAxisLock::Start` --> `EAxisLock::START`).

Remove redundant part of `enum class` name from literal names (e.g. `EDragSide::SIDE_BOTTOM` --> `EDragSide::BOTTOM`, `EAxis::AXIS_X` --> `EAxis::X`, `EEnvelopeEditorOp::OP_SELECT` --> `EEnvelopeEditorOp::SELECT`, `EQuadPointProp::PROP_POS_X` --> `EQuadPointProp::POS_X`).

Add consistent trailing comma for last literal.
