Move Flag, Debug, Ctxt, Exit, and error messages to
new package cmd/compile/internal/base.
These are the core functionality that everything in gc uses
and which otherwise prevent splitting any other code
out of gc into different packages.
A minor milestone: the compiler source code
no longer contains the string "yy".

This commit contains the compiler support for //go:embed lines.
The go command passes to the compiler an "embed config"
that maps literal patterns like *.txt to the set of files to embed.
The compiler then lays out the content of those files as static data
in the form of an embed.Files or string or []byte in the final object file.
The test for this code is the end-to-end test hooking up the
embed, cmd/compile, and cmd/go changes, in the next CL.
For #41191.
