Our approach to commands and their arguments has been ad-hoc until this
point. This CL creates a standard way of defining and passing the
arguments to different commands. The arguments to a command are now
json.RawMessages, so that we don't have to double encode. This also
allows us to check the expected number of arguments without defining
a struct for every command.

This change moves the suggested fixes logic for fillstruct out of the
analysis and into internal/lsp/source. This logic is then used as part
of a new fillstruct command. This command is returned along with the
code action results, to be executed only when the user accepts the code
action.
This led to a number of changes to testing. The suggested fix tests in
internal/lsp doesn't support executing commands, so we skip them. The
suggested fix tests in internal/lsp/source are changed to call
fillstruct directly. A new regtest is added to check the command
execution, which led to a few regtest changes.
Also, remove the `go mod tidy` code action, as it's made redundant by
the existence of the suggested fixes coming from internal/lsp/mod.

We use file identities pervasively throughout gopls. Prior to this
change, the identity is the modification date of an unopened file, or
the hash of an opened file. That means that opening a file changes its
identity, which causes unnecessary churn in the cache.
Unfortunately, there isn't an easy way to fix this. Changing the
cache key to something else, such as the modification time, means that
we won't unify cache entries if a change is made and then undone. The
approach here is to read files eagerly in GetFile, so that we know their
hashes immediately. That resolves the churn, but means that we do a ton
of file IO at startup.
Incidental changes:
Remove the FileSystem interface; there was only one implementation and
it added a fair amount of cruft. We have many other places that assume
os.Stat and such work.
Add direct accessors to FileHandle for URI, Kind, and Version. Most uses
of (FileHandle).Identity were for stuff that we derive solely from the
URI, and this helped me disentangle them. It is a *ton* of churn,
though. I can revert it if you want.

on a cache and exposing the unique identifier for all the objects, both
of which are useful and reasonable things to have in the API anyway.
