Test spin build error. See:

Building component tinygo-mysql with `tinygo build -target=wasi -gc=leaking -o main.wasm main.go`
# github.com/fermyon/spin/sdk/go/mysql
../../../../../../opt/homebrew/Cellar/tinygo/0.30.0/lib/clang/include/stdbool.h:20:14: undefined: C._Bool
Error: Build command for component tinygo-mysql failed with status Exited(1)

I create a issue on Tinygo tinygo-org/tinygo#3926 .

Thanks for this, and for flagging the upstream problem to the TinyGo folks - looks like they already have a fix so hopefully in the next version...

@adamreese PTAL

Looks great! I tested out on TinyGo dev. We need to wait to merge until the C._Bool issue is released in TinyGo.

@Patrick0308 I think a rebase will take care of the weird wit-bindgen compilation errors in CI. Thanks for sticking with this!

@adamreese @itowlson I replaced C._Bool to bool then testing the program went smoothly. So we don't need to wait util tinygo-org/tinygo#3926 is released.

Thanks for your great work on this feature! This is awesome
