Revert "Update the tests (ISO-8859-1 => windows-1252)"

This reverts commit 9c188b20fbb4d4c2006ab1a611ed8a9b971e7cee.

Broke several browser_tests which depended on the previous behavior:
BrowserEncodingTest.TestOverrideEncoding
EncodingAliases/BrowserEncodingTest.TestEncodingAliasMapping/16
BrowserEncodingTest.TestEncodingAutoDetect
EncodingAliases/BrowserEncodingTest.TestEncodingAliasMapping/3

E.g.

- PASS: windows-1252
+ PASS: ISO-8859-1
 This test baselines charset sniffer behavior where the opening bracket inside a tag is consumed as part of the tag data, causing the meta tag to be missed.

 This test demonstrates that we don't buffer HTML documents looking for a meta charset directive. Instead, we follow the HTML5 specification and switch encoding mid-parse. The iframe below should alert two different encodings.
