[4.x] [gen3] fixes interrupts() API, should not clear pending interrupts

[technobly]

Problem

• [gen3] interrupts() API should not clear pending interrupts

Solution

• [gen3] pending interrupts was being cleared unintentionally. Simply removing the clearPending call resolves it.

Steps to Test

• run TEST=app/interrupts on all platforms, jumpering a wire from A5 to D0 ~ D6 one at a time and resetting the device between tests.
