Make "CMake: Add ... Preset" commands available when useCMakePresets is auto (#4722)

* Initial plan

* feat: make Add Preset commands available when useCMakePresets is auto

When cmake.useCMakePresets is set to "auto" and no CMakePresets.json
exists yet, the "Add ... Preset" commands are now available in the
command palette. A new context key cmake:addPresetCommandsAvailable
is set to true when the setting is not explicitly "never", allowing
users to create preset files from the command palette.

Fixes #2411

+- Make "CMake: Add ... Preset" commands available in the command palette when `cmake.useCMakePresets` is set to `auto`, even before a CMakePresets.json file exists. [#4401](https://github.com/microsoft/vscode-cmake-tools/issues/4401)
 - Improve CMake syntax highlighting with command-scoped keyword rules, expanded variable recognition, and better generator-expression support. Remove obsolete deprecated-keyword entries that caused false positives on user-defined names.
