Correct duplicate "is is" word found in 181 files throughout the codebase. In most cases "is is" was changed to "is", but in contexts like "MCU is is sleep mode" it was corrected to "MCU in sleep mode". Also fixes a "the the" typo in net/inet/inet_sockif.c. This is a pure style/documentation fix that improves code readability. Signed-off-by: Huang Qi <huangqi3@xiaomi.com>
