0026290: It is neccessary to separate visualization part from TKCAF

Browse Source 
- Package TPrsStd is moved into new toolkit TKVCAF. This is the only toolkit in OCAF that depends on visualization libraries.

- All persistent data stored in TPrsStd_AISPresentation attribute are moved to new attribute TDataXtd_Presentation, which is maintained automatically on the same label as TPrsStd_AISPresentation.
All parameters used by TPrsStd_AISPresentation are stored in corresponding TDataXtd_Presentation attribute.

- TPrsStd_AISPresentation is not stored in file any more; when OCAF document is loaded from a file, these attributes are created at all labels where TDataXtd_Presentation attribute is located, by TPrsStd_AISViewer::New().

- File src/StdResources/MigrationSheet.txt necessary for reading files written by previous versions of OCCT (lost in one of previous integrations) is restored and updated as necessary to handle this change (defines replacement of TPrsStd_AISPresentation by TDataXtd_Presentation). Environment variable CSF_MIGRATION_TYPES should be defined, pointing to this file.

- Packages BinMPrsStd and XmlMPrsStd are removed; their drivers are moved into BinMDataXtd and XmlMDataXtd respectively.

- Version numbers of BinOCAF and XmlOCAF formats are increased, new files cannot be read by previous versions of OCCT

- New tests added

- Adding new TKVCAF toolkit in sample projects

- Restore IsDisplayed(false) in TPrsStd_AISPresentation::Erase()

Related classes (AIS_LocalContext) and methods (AIS_InteractiveContext::OpenLocalContext() and others) will be removed within some future OCCT release.
The main functionality provided by Local Context - selection of object subparts - can be now used within Neutral Point without opening any Local Context.
@subsection upgrade_occt700_separate_caf_visualisation Separation of visualization part from TKCAF
Visualization CAF attributes moved into new toolkit TKVCAF.
If your application uses the classes from TPrsStd package then add link to TKVCAF library.
Verson numbers of BinOCAF and XmlOCAF formats are incremented; new files cannot be read by previous versions of OCCT.
For loading OCAF files saved by previous versions and containing attribute TPrsStd_AISPresentation it is necessary that environment variable CSF_MIGRATION_TYPES should be defined, pointing to file src/StdResources/MigrationSheet.txt.
When using documents loaded from a file, make sure to call method TPrsStd_AISViewer::New() prior to accessing TPrsStd_AISPresentation attributes in this document (that method will create them).
