Remove 2 duplicated SVG tests and rename 3 SVG text tests for selection

Remove 2 duplicated SVG tests and rename 3 SVG text tests for selection

This patch removes the following W3C-SVG-1.1 tests in favor of their
duplicated versions in W3C-SVG-1.1-SE and renames the following SVG
text tests because they are actually testing selection. The
associated expectation files have been updated as well.

Remove (W3C-SVG-1.1)
1. text-intro-02-b.svg
2. text-intro-05-t.svg
3. text-intro-02-b-expected.png
4. text-intro-02-b-expected.txt
5. text-intro-05-t-expected.png
6. text-intro-05-t-expected.txt

Rename (text)
1. text-intro-05-t.svg -> text-selection-intro-05-t.svg
2. text-path-01-b.svg -> text-selection-path-01-b.svg
3. text-spacing-01-b.svg -> text-selection-spacing-01-b.svg
4. text-intro-05-t-expected.png ->
                   text-selection-intro-05-t-expected.png
5. text-intro-05-t-expected.txt ->
                   text-selection-intro-05-t-expected.txt
6. text-path-01-b-expected.png ->
                   text-selection-path-01-b-expected.png
7. text-path-01-b-expected.txt ->
                   text-selection-path-01-b-expected.txt
8. text-spacing-01-b-expected.png ->
                   text-selection-spacing-01-b-expected.png
9. text-spacing-01-b-expected.txt ->
                   text-selection-spacing-01-b-expected.txt

For the /text tests, please see my comments in
https://codereview.chromium.org/1049863003

The changes for text-intro-02-b.svg and text-intro-05-t.svg look fine but we'll
need to update the expectation files as well.
