Added more debug color variables

[leidegre]

This PR adds additional global variables for debug view, these are the ones I could find that were constants or involved constants somehow by pulling all these into variables you can now convert these variables from 8-bit to whatever your rendering backend uses, I have for example the following snippet in my Clay program for which makes the debug view render nicely (I use a custom Direct2D based backend and not Raylib). This backend uses color values in the range of 0 to 1.

The following may be suitable to make into a Clay utility function that does this conversion for you, which can be called to normalize color values if that is what you want for your backend.

#define CLAY_COLOR_NORMALIZE(c,n) (Clay_Color){c.r/n,c.g/n,c.b/n,c.a/n}

CLAY__DEBUGVIEW_COLOR_1=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_1,255.0f);
CLAY__DEBUGVIEW_COLOR_2=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_2,255.0f);
CLAY__DEBUGVIEW_COLOR_3=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_3,255.0f);
CLAY__DEBUGVIEW_COLOR_4=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_4,255.0f);
CLAY__DEBUGVIEW_COLOR_CLOSE_BUTTON_1=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_CLOSE_BUTTON_1,255.0f);
CLAY__DEBUGVIEW_COLOR_CLOSE_BUTTON_2=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_CLOSE_BUTTON_2,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_BACKGROUND_ALPHA/=255.0f;
CLAY__DEBUGVIEW_COLOR_TYPE_RECTANGLE=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_RECTANGLE,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_TEXT=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_TEXT,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_IMAGE=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_IMAGE,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_FLOATING_CONTAINER=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_FLOATING_CONTAINER,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_SCROLL_CONTAINER=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_SCROLL_CONTAINER,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_BORDER_CONTAINER=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_BORDER_CONTAINER,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_CUSTOM=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_CUSTOM,255.0f);
CLAY__DEBUGVIEW_COLOR_TYPE_ERROR=  CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_TYPE_ERROR,255.0f);
CLAY__DEBUGVIEW_COLOR_SELECTED_ROW=CLAY_COLOR_NORMALIZE(CLAY__DEBUGVIEW_COLOR_SELECTED_ROW,255.0f);
Clay__DebugView_TextNameConfig.textColor=CLAY_COLOR_NORMALIZE(Clay__DebugView_TextNameConfig.textColor,255.0f);

Feel free to merge this or don't, I just wrote this up as a suggestion. If it doesn't make sense no worries.
