Newly installed versions of the engine will now attempt to copy the project-agnostic config settings from a previous engine installation. This happens by way of a versioned manifest that copies old versions when the manifest does not exist, or is a different version. This code path is benign for non-installed versions of the engine (or FPaths::ShouldSaveToUserDir() is false).
EditorGameAgnosticSettings and EditorUserSettings ini paths have been renamed to EditorSettings and EditorPerProjectUserSettings respectively to better convey their purpose. In general, most settings should be saved in EditorSettings (project-agnostic) so that they apply regardless of which project is open. We have some way to go migrating existing settings for this to be the case, however.
Some previously per-project configuration files are now project-agnostic (such as Editor.ini, EditorKeyBindings.ini, and EditorLayout.ini)
GEditor->Access...Settings and GEditor->Get...Settings have been removed in favor of direct access of the CDO through GetMutableDefault<> and GetDefault<> respectively. Global config ini filenames that are not set up are now neither loaded nor saved on build machines, to handle the problem of indeterminate state more generically.
This addresses UETOOL-270 (Most editor preferences should be project-agnostic)

Most code accessing brush/landscape data by calculating indexes (e.g. Data + (Y-Y1)*XSize + (X-X1)) replaced with scanline[X] style for speed
LandscapeInfo->SelectedRegion is now only queried if it contains anything, to avoid hashing the key unneccessarily (the hash function was showing on profiles :( )
Smoothing tool's SmoothFilterKernel*Scale* replaced by the more intuitive Size
Component brush fixed to be properly centered on the cursor at odd sizes and work correctly with the add component tool when cursor is over the landscape (but part of the brush is off the landscape) and size is >1
Copy tool fixed to copy the selected area and not a circle when using ctrl+c
Also a few style cleanups. for (auto it = xyz.CreateIterator...) replaced with ranged for, enums replaced with enum classes, 0.f -> 0.0f, NULL->nullptr, etc.

Fix crash when replacing material in the "New Landscape" panel with one with fewer material layers (or null)
Fix undo transactions for "interactive" changes (e.g. sliding sliders) so they don't flood the undo buffer with one transaction for every sub-step of the change

Breaking changes include:
* Rename of GEditorModeTools -> GLevelEditorModeTools to signify that it applies only to the level editor modes
* Addition of FEditorModeRegistry, responsible for managing and creating new editor modes. Modes are no longer registered with an instance of the mode, instead with a mode factory that is able to create a new mode of that type.
* Editor modes now operate on FEditorViewportClients rather than FLevelEditorViewportClients
* Added ability to specify an FEditorModeTools when creating an FEditorViewport
Moved component vizualiser manager handling outside of individual editor modes, and into FLevelEditorViewportClient. This should make it easier to transplant in future.
This work addresses TTP#334640 - EDITOR: Investigate making editor modes a per-'editor' concept

#summary Rename Trunc, Round, Floor, Ceil to TruncToInt, RoundToInt, FloorToInt, CeilToInt. Added *ToFloat versions. Repeated for FGenericPlatformMath and all derived classes for all platforms wherever applicable. Corrected comment in Fractional and added Frac() which does HLSL-style fractional (x - floor(x)). Checked for compilation on all projects (with cooking levels wherever applicable). Didn't change Fractional to Frac, this will be done in second commit.
