Code actions that apply convenience fixes were filtered by the start
line so it wasn't possible to narrow the scope to a specific range.
This change allows clients to send a specific range (or cursor position)
to filter all fixes where the range doesn't intersect with the provided
range. It also widens the diagnostic returned by fillstruct analysis.
The idea is to provide a way to narrow the scope without breaking
clients that do want to ask for code actions using the entire line.

The logic for extracting a function is quite signficant, and the code
is expensive enough that we should only call it when requested by the
user. This means that we should support extracting through a command
rather than text edits in the code action.
To that end, we create a new struct for commands. Features like extract
variable and extract function can supply functions to determine if they
are relevant to the given range, and if so, to generate their text
edits. source.Analyzers now point to Commands, rather than
SuggestedFixFuncs. The "canExtractVariable" and "canExtractFunction"
functions still need improvements, but I think that can be done in a
follow-up.

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.

The previous implementation did not support filling anonymous structs.
This is distinct from filling a struct that has an anonymous
struct as a field. That field will still not be filled.
golang/go#39929 has been opened to address this limitation.

Getting the right indentation for the text in the AST proves to be a
little complicated. The most reasonable approach seems to be writing
out the AST, getting the lines with the struct definition on it,
and trimming whitespace to get the current indent. Then, we add this
indent to the struct fields in the new text.

of creating new AST nodes.

Now that fillstruct is an analyzer, we can simplify the code that calls
it in code_action.go. We introduce a new class of analyzer --
convenience analyzers, which are closer to commands. These represent
suggestions that won't necessarily improve the quality or correctness of
your code, but they offer small helper functions for the user.
This CL also combines the refactor rewrite tests with the suggested fix
tests, since they are effectively the same.
For now, we only support convenience analyzers when a code action was
requested on the same line as the fix. I'm not sure how to otherwise
handle this without bothering the user with unnecessary diagnostics.

The current implementation of the fill struct tool is not a part of
the analysis framework. This commit moves the functionality from the
source directory to the analysis directory.
