Closes #10300: Fix Baidu search telemetry

[rxumoz]

Since there might be two types of urls from Baidu (https://m.baidu.com/s?from=... or https://m.baidu.com/from=*/s?), this patch handles baidu separately in Utils.kt

However, there is still a problem that the codes from Baidu are started with numbers (e.g. 844b/1000969a/...), which would be regarded as invalid characters by Glean.

Need more discussion about this, so leave it a draft.

Since the problem of Baidu that the codes start with figures, I add prefix to these codes with "_"

I can imagine us assigning this to a codeParam variable. I wonder how far that could get us without introducing the originalCode, but continuing to modify code.

[rxumoz]

I don't quite get. Do you mean adding the "_" after the codeParam, or adding other parameters in SearchProviderModel apposed with codeParam?
