Jay Conrod 434cdd0337 debug/buildinfo: new package with Read and ReadFile
These functions provide access to module information stamped into Go
binaries. In the future, they'll provide access to other information
(like VCS info).

These functions are added in a new package instead of runtime/debug
since they use binary parsing packages like debug/elf, which would
make runtime/debug an unacceptably heavy dependency. The types in
runtime/debug are still used; debug/buildinfo uses them via type
aliases.

This information is already available for the running binary through
debug.ReadBuildInfo and for other binaries with 'go version -m', but
until now, there hasn't been a way to get it for other binaries
without installing cmd/go.

This change copies most of the code in cmd/go/internal/version. A
later CL will migrate 'go version -m' to use this package.

For #37475
Fixes #39301
