Added localization for all .razor pages.
Added Language Model in Shared Project.
Add LocalizationConstants in shared project.
Add DI to all razor pages for injection for resources.
Add Resource Project directory in Blazor Client, and organized the .resx files accordingly.

To Add new translation, Add a new LanguageCode entry to LocalizationConstants, will be auto added to dropdown when app start up, and available in language selection.
Add new .resx files with the post-text of the Code in Language Code eg. en-US, add File Login.en.resx in appropriate directory. Easier, copy existing file and rename with the new code, and change the values for localization.

@fretje @iammukeshm , can the PR please be checked, comments is welcome. Reason for adding in shared, I want to translate the Api services later-on as well using resx. I only added English and Afrikaans to xlates, as this is current languages that will be used for now in project, but can be expanded, as we have 11 official languages.
