Text update

[Insality]

Scale mode: not only downscale, add text trim

Add scroll for trimmed text

[Insality]

Possibly, trim mode can be add with styles
no_adjust can be removed from component init params

Variants of text adjust modes:

• Downscale (current)
• Trim (remove outside text with "..."). Add ability to scroll this text?
• No adjust - remove all component adjust behaviour
• Scrolling text with stencil? Scroll in some direction with some pattern

Update Text component:
- Add text adjust type instead of no_adjust param.
- const.TEXT_ADJUST.DOWNSCALE - Change text's scale to fit in the text node size
- const.TEXT_ADJUST.TRIM - Trim the text with postfix (default - "...", override in styles) to fit in the text node size
- const.TEXT_ADJUST.NO_ADJUST - No any adjust, like default Defold text node
- const.TEXT_ADJUST.DOWNSCALE_LIMITED - Change text's scale list downscale, but there is limit for text's scale
- const.TEXT_ADJUST.SCROLL - Change text's pivot to imitate scrolling in the text box. Use with stencil node for better effect.
- const.TEXT_ADJUST.SCALE_THEN_SCROLL - Combine two modes: first limited downscale, then scroll
