Add auto-hide option to toolbars

[gwigz]

Toggled per edge (left/right/bottom/top) via the toolbar context menu, backed by the AlchemyToolbarAutoHide{Left,Right,Bottom,Top} settings (default off).

Skips rendering while completely hidden.

📝 Walkthrough

Walkthrough

Four persisted boolean settings (AlchemyToolbarAutoHideLeft/Right/Bottom/Top) are added to settings_alchemy.xml. lltoolbarview.h gains an AutoHideEdge struct and private helper declarations. lltoolbarview.cpp adds anonymous-namespace helpers, extends postBuild and draw(), and implements the slide animation using frame-timer interpolation and per-side hot-zone detection. The toolbar context menu exposes the four options as checkable items.

Changes

Toolbar Auto-Hide Slide Animation

Layer / File(s)	Summary
Settings definitions and context menu UI indra/newview/app_settings/settings_alchemy.xml, indra/newview/skins/default/xui/en/menu_toolbars.xml	Four persisted boolean settings (default 0) are added; four checkable "Auto-hide" menu items are inserted into the Toolbars Popup, each using ToggleControl/CheckControl wired to the matching setting.
AutoHideEdge struct and class declarations indra/newview/lltoolbarview.h	Forward-declares LLLayoutPanel, introduces the AutoHideEdge state struct (panel pointer, full/visible dimensions, offset, last hover time), declares five new private helper methods, and adds the mAutoHideEdges array member.
Anonymous-namespace helpers and postBuild initialization indra/newview/lltoolbarview.cpp	Adds llcriticaldamp.h include, defines constants and helper functions mapping toolbar locations to settings keys, computing slide-axis dimensions, and detecting forced-visibility conditions. Extends postBuild to assign mAutoHideEdges[*].panel for all four sides and seed full_dim/visible_dim.
draw() integration and core auto-hide logic indra/newview/lltoolbarview.cpp	draw() now calls updateAutoHide() each frame, clears prior offsets, applies new offsets, and toggles parent panel and toolbar visibility via base_visible/fully_hidden. Implements getAutoHideEnabled, isMouseInRevealZone (per-side hot-zone geometry), updateAutoHide (frame-timer interpolation with linger), clearAutoHideOffset, and applyAutoHideOffset.

Poem

🐇 Hop along, the bars shall hide,
Tucked away until you glide,
A whisker's width from screen's near edge,
They spring back out upon the ledge!
Settings saved, the menu blessed—
Auto-hide puts toolbars to rest. ✨
