Refactor CMake build settings

Add support for all generators to CMake build settings

Correct command line option for CMake's --warn-unused-vars

Rename clean command to clean target to better reflect its use as
the argument passed to cmake's --target command line.

Add all target for the argument passed to cmake's --target
command line when doing a normal build.

Clarify usage of UI overrides and change the UI to be "use defaults"
(i.e. invert the checkbox). This is a **breaking** change as it means
user projects that were using UI overrides will revert to using defaults.
This is done on purpose as so many little things have changed in CMake
settings, that reverting to defaults on upgrade seems like a logical
decision. In addition *use defaults* matches the other GUIs in Eclipse,
for example the MBS build command settings.

Populate all default in getDefaultProperties() so that all CMake build
settings are displayed as used (greyed out) and can be used as a starting
point when editing settings.

Simplify some of the code in CMakeBuildTab, especially:
- removing the duplicated code between initializeFrom and
restoreProperties
- use Map's getOrDefault instead of a get, followed by a null check.

Remove getUseDefaultCommand/setUseDefaultCommand as they don't appear
in the GUI and it makes it impossible for the GUI command to be used.
It is also redundant as use ui overrides is a global use default for
all settings, so having a second use default seems unneeded at this point.

Cleanup and simplify getCMakeProperties.

Fix parsing of extra args so that quoted strings work.

Remove doubled-up extra args added to command line.

Refactored manual tests document and brought it up to date.

 # Core Build
 
+## More CMake build settings are now available in the user interface
+
+The CMake build setting GUI has been updated to include more CMake settings, and some of the settings that did not used to do the correct thing have been updated for more consistent behavior.
+The way these settings are saved has been slightly modified, meaning workspaces with CMake projects from before CDT 12 will have their build settings restored to defaults.
+Build settings can be customized by unchecking "Use default CMake settings".
+
+TODO: Before release add the final screenshot for the build settings here. I am not including it now because the UI keeps changing.

 ## Default build system generator for CMake changed to Ninja on all platforms
 
 The default for CMake's  build system generator is now Ninja on all platforms.
 Users who want to use other build system generators can select their desired generator in the build settings.
