[ENGG-1977] MV3: 2KB limit for regexFilter in DNR

When creating host regex rules Unchecked runtime.lastError: Rule with id 1 was skipped as the "regexFilter" value exceeded the 2KB memory limit when compiled. Learn more: https://developer.chrome.com/docs/extensions/reference/api/declarativeNetRequest#regex-rules

Possible Solutions

1. Using URL source conditions instead of HOST source conditions

If you are using HOST - EQUALS | CONTAINS | MATCHES | WILDCARD, then try switching it to URL source condition.

2. Try using Redirect Rule

Almost all the usecases that are supported by replace rule are also supported by Redirect Rule . Try creating a redirect rule instead

Some patterns to convert Replace rule into Redirect rule

Pattern 1

Current Replace Rule

Converted Redirect Rule

Pattern 2

Current Replace Rule

Converted Redirect Rule

Start by reproducing the Chrome declarativeNetRequest error with host-based regex rules and review the linked regex-rules documentation. Compare the suggested URL source conditions and redirect-rule approach against the affected replace-rule use cases. Done means supported rules no longer exceed the 2KB compiled regexFilter limit.
