Add GPIO interrupt for ESP32C3

[zdima]

I have stumble upon compiler issue related to interrupts.
This is a test branch with working pininterrupt test.
If you uncomment one case (5) in switch statement the tinygo will start failing in link with missing symbols.
And if you uncomment more cases (like 1-5) in switch statement the tinygo will just crash.
I am using LLVM13 build with make make llvm-build and make to build tinygo:

arm64:pininterrupt zdima$ tinygo version
tinygo version 0.23.0-dev-a7a69d38 darwin/arm64 (using go version go1.17.3 and LLVM version 13.0.0)

$ tinygo flash -x -target=esp32c3-12f pininterrupt.go
