Update en_US and pt_BR

**en_US**
Update according to https://github.com/hrydgard/ppsspp/pull/3603.


**pt_BR**
Translation of more terms.

I did not translate "Debugging" menu, because most terms are technical and a literal translation would not be good. Users that understand these options usually do not have problems with English, while common users would only use these options following a tutorial and they would not understand the meaning in any language.
