Adjust the UI of dlgInternal and specific color selector

For most artists, the common selector for color selection should be the color wheel, so the color wheel and color palette are combined into a tab, and the color wheel is set as the default page, which helps to save screen space and add subsequent selectors, such as color history; changed the spinnbox color selector to a box that can be dragged to input, so that we can use a digital pen to adjust the value

For specific color selector, added the color preview of the previous selection, click it to return to the color of the previous selection, move the selection item of HSX to the pop-up panel, and remove the percentage option button, because we can set the color space as a floating point number to achieve the same effect. When the color space is no longer rgb, the hex and hsx selectors will not be hidden, so that the hex and hsx selectors can be used to input colors in other non rgb color spaces; the adjustment button in the input box is removed, but it can be adjusted by clicking on the left and right sides of the slider with Shift and Alt. When pressing Shift and clicking on the left half of the slider, the total range will be reduced in steps of 0.1, while the right half will be increased; step is 1 when pressing and holding alt and clicking.
