The drive long welcome banner is removed and the new GM2 looks applied
to drive welcome banner and drive and download warning banners.

Also Dismiss buttons changed from X to text buttons.

Modified cr-button is used for text buttons. cr-button provides most of
the text button styles, specially ripple (inkdrop) effect.

The changed css classes duplicated for existing UI and
files-ng with body:not(.files-ng) and body.files-ng prefixes
respectively.

The icon/logo changed to svg version.

rtl/ltr direction tested. It's supported in this CL by using flex
system and inline start/ends rules while the non-filesng uses dir
attribute and absolution positioning. It helps to reduce the complexity
by using one set of rules for both directions.

For files-ng clean up:
- js: can be caught where isFilesNG() method used
- css: body:not(.files-ng)
- Other: ToDos added in string resource files
