Move the code that opens and increments counters out of the
cmd/internal/telemetry package into cmd/internal/telemetry/counter. The
telemetry package has dependencies on the upload code, which we do not
want to pull into the rest of the go toolchain.

Add cmd/internal/telemetry to cmd/dist's bootstrapDirs so it's built
when bootstrapping the compiler. cmd/internal/telemetry is a wrapper
arount telemetry functions that stubs out the functions when built in
bootstrap mode to avoid dependencies on x/telemetry in bootstrap mode.
Call telemetry.Start with an empty config to open the counter file, and
increment a counter for when the command is invoked.
After flags are parsed, increment a counter for each of the names of the
flags that were passed in. The counter names will be compile/flag:<name>
so for example we'll have compile/flag:e and compile/flag:E.
In FatalfAt, increment a stack counter for internal errors.

ErrorfVers used to be used by typecheck to report when new language
functionality was used, but the -lang flag (from go.mod) was set to an
older version. However, all of the callers have been since removed,
now that this is handled by types2.
And for the same reason, we can stop changing base.Flag.Lang. This was
previously a workaround so that the unified frontend could generate
arbitrary IR without upsetting typecheck, at a time when typecheck was
itself a real frontend. Now it's just a glorified desugaring pass.

In the type checkers, add Config.ErrorURL (or Config._ErrorURL for
go/types) to configure whether and how an error message should report
a URL for errors that have an error code.
In the compiler, configure types2 to report an error URL of the form
" [go.dev/e/XXX]", where XXX stands for the error code, with the URL
appended to the first line of an error.
Rename the compiler flag -url to -errorurl. At the moment this flag
is disabled by default.
Example for a one-line error message:
<pos>: undefined: f [go.dev/e/UndeclaredName]
Example for a multi-line error message:
<pos>: not enough arguments in call to min [go.dev/e/WrongArgCount]

If the -url flag is provided, when encountering a type checking error,
the compiler will also print a URL to a more detailed description of
the error and an example, if available.
Example uses:
go tool compile -url filename.go
go build -gcflags=-url pkg/path
For instance, a duplicate declaration of an identifier will report
https://pkg.go.dev/internal/types/errors#DuplicateDecl
We may refine the provided URL over time.

Pass type checker error codes to base.ErrorfAt function calls
in the compiler (but don't do anything yet with the code).
Also, provide error codes to base.ErrorfAt calls in the
compiler as needed.
This opens the door towards reporting the error code and/or
providing a link/reference to more detailed explanations
(see internal/types/errors/codes.go).

We have almost 200 uses of the "assert" helper functions in noder and
typecheck. Clearly the tiny bit of extra convenience of writing a
one-line assertion rather than an if+panic is helpful, so we might as
well add functions for this to base itself so that it's easier to
write more informative error messages.

Move Flag, Debug, Ctxt, Exit, and error messages to

These are the core functionality that everything in gc uses
