internal/sarif: add code flows

A code flow is a compact representation of a trace used for the textual
output of govulncheck. For that purpose, the logic for trace compaction
is extracted into a separate internal package traces.

We also add the message portion of Location object for code flows to
reduce the number of CLs; the actual physical region part will come in
following CLs. To make things consistent, we also add the Message part
of the location for stacks.

Go Vulnerability Management

Go Reference

Go's support for vulnerability management includes tooling for analyzing your codebase and binaries to surface known vulnerabilities in your dependencies. This tooling is backed by the Go vulnerability database, which is curated by the Go security team. Go’s tooling reduces noise in your results by only surfacing vulnerabilities in functions that your code is actually calling.

You can install the latest version of govulncheck using go install

go install golang.org/x/vuln/cmd/govulncheck@latest

Then, run govulncheck inside your module:

govulncheck ./...

See the govulncheck tutorial to get started, and https://go.dev/security/vuln for more information about Go's support for vulnerability management. The API documentation can be found at https://pkg.go.dev/golang.org/x/vuln/scan.
