Reviewed by Dmitry Titov.
The following semantic is adopted per the discussions on public-webapps:
1) File.slice() does a synchronous IO to capture the current size and
modification time and cache them in the resulting Blob.
2) Subsequent Blob operations, like Blob.slice and Blob.size simply
use the cached values.
3) When the underlying file data are accessed, like in XHR.send(), the
UA will check the cached modification time against the current
modification time to determine if the file has been changed or not.
An error or exception will be thrown if needed.
Also add ENABLE_BLOB_SLICE feature define.

LayoutTests: Blob.slice support.
https://bugs.webkit.org/show_bug.cgi?id=32993
Reviewed by Dmitry Titov.
Add a new layout test to test slicing and sending a file. In addition,
two new scripts are introduced to create and touch the temp file.
Move some code from send-dragged-file.js to a new file
setup-file-input-element-for-drag.js so that it can be used by both
send-dragged-file.js and send-sliced-dragged-file.js to setup the input
element for the file dragging.
Since the Blob.slice is only enabled for Mac, we disable the new test
for all other platforms.

+ Blob.slice support.
+ https://bugs.webkit.org/show_bug.cgi?id=32993
+
+ The following semantic is adopted per the discussions on public-webapps:
+ 1) File.slice() does a synchronous IO to capture the current size and
+ modification time and cache them in the resulting Blob.
+ 2) Subsequent Blob operations, like Blob.slice and Blob.size simply
+ use the cached values.
+ 3) When the underlying file data are accessed, like in XHR.send(), the
+ UA will check the cached modification time against the current
+ modification time to determine if the file has been changed or not.
+ An error or exception will be thrown if needed.
+
+ Also add ENABLE_BLOB_SLICE feature define.
+
+ Test: http/tests/local/send-sliced-dragged-file.html
