Add new macro WorkspaceRealPath

The WorkspaceRealPath macro is identical to WorkspacePath - but just expanded/converted by calling FileUtils::RealPath (realpath()) - this means that any symlink present in the path is resolved.

Reasoning for introduction of WorkspaceRealPath macro:

I have a number of (FSW) projects that have to be placed on a network drive with a special and extremely long/deep directory layout (not my choice)

In order to eliminate the long/deep path leading to the project dirs of these projects - I have created a local project root with symlinks to the real projects - mission accomplished...

This has worked well with CodeLite until the switch from ctags to clangd (LSP)...

Here is an example of one the problems (there are actually more):

Clangd (LSP) returns filepaths as expanded (real)paths.

With a FSW project opened with a shortend (symlink) path - the Workspace pane file-tree does not recognize the expanded (real)path as a part of the FSW project - and hence it will not sync the file returned by LSP with the workspace pane file-tree.

But clangd (LSP) has a fix for that - path-mappings will translate a remote path into a local path (just what we (I) need)

By adding the following into the clangd (LSP) command every thing works again:

--path-mappings=$(WorkspacePath)=$(WorkspaceRealPath)

Summary:

By introducing the WorkspaceRealPath macro the problems of mapping between "virtual" symlink paths and (real)paths are automatically handled

Nice! I have been struggling with similar issue myself :) (I am using FSW with SSH)
At work, my home drive is /local/home/... so clangd resolves all the path to their real paths, so i might end up with 2 files opened at CodeLite the one with realpath and the symlinked, sounds like your fix will resolve both issues

Thanks for merging 👍

BTW: I have a few other patches that may be needed to cover all scenarios where editor ends up opening 2 tabs for the same file... but they need a little clean up before they can become into PR's :-)
