matloob 4c20f7f15a cmd/cgo: run gcc to get errors and debug info in parallel
This change kicks off the work to load the debug info when processing
each file, and then waits for all the files to be processed before
starting the single-goroutined part that processes them. The processing
is very order dependent so we won't try to make it concurrent. Though
in a later CL we can wait for only the relevant package to have been
processed concurrently before doing the single-goroutined processing for
it instead of waiting for all packages to be processed concurrently
before the single goroutine section.

We use a par.Queue to make sure we're not running too many gcc compiles
at the same time. The change to cmd/dist makes the par package available
to cgo.

Fixes #75167
