* Write PrimaryProjectPath.txt with the location of the solution, this could be different than the root depending on project gen arguments
* Update SourceCodeAccessor accordingly to get the correct path to the solution, maintaining old defaults if the PrimaryProjectPath.txt file is not found

This function is shared by the DTE and non-DTE code paths, so needs to be available when WITH_VISUALSTUDIO_DTE is false to avoid a linker error

Note: _MSC_VER is still 1929 with the VS2022 preview, I expect it to be 1930 eventually when the compiler version is bumped which should match the versioning scheme for every other VS release

Use FUProjectDictionary singleton to eliminate needless Refresh() inside DoesSolutionExist()/GetSolutionPath() queries.
The code accessors want to discover the active game project solution/project, which should exist at editor launch time. We don't need the more recent refreshes from the temporary stack instances of FUProjectDictionary.
