Walk the whole decompiler pipeline in the Debug Steps pane

The pane used to split the pipeline across two languages: the ILAst language
stepped the IL transforms, the C# language stepped the AST transforms, and
nothing showed the seam between them, so a step index meant a different thing
depending on which language happened to be selected. Recording both halves into
one Stepper makes an index replayable across the whole pipeline; a limit that
lands in the IL phase has no C# to print, so the halted function is rendered as
ILAst instead.

Which function that is takes some care, because a member group's EndStep is the
next member's first step: a halt standing on a member's opening step belongs to
the member that just finished, a transform that throws where the limit was aimed
has to hand over the ILAst it half-transformed (what the ILAst language showed
as "ILAst after the crash"), and a step recorded on a helper function the
pipeline has not attached yet belongs to that function's own tree.

Retention stays opt-in twice over: the decompiler records IL steps only when
asked to, and the pane asks only while its view is on screen. Every kept step
pins the ILAst it captured, which for one type runs to tens of thousands of
nodes, so a closed pane would be paying for a tree nobody displays.

What is left of the ILAst language is its typed-IL dump, which runs no
transforms at all. That stays, as TypedILLanguage. IDebugStepProvider was down
to a single implementation and is removed.

Fix #3510 : keep exporting a project when a member cannot be decompiled

One member the decompiler could not handle aborted the whole export, so a
single unsupported method in a large assembly left the user with nothing: no
sources, no .csproj, no way around it. Recovering silently would trade that
for a worse outcome - broken output nobody knows is broken - so every failure
is recorded, written where the content would have gone, and pointed at the
issue tracker.

The recovery has to hold for anything the export touches, not just method
bodies: a file that cannot be created, a resource that cannot be decoded, an
output visitor that throws mid-type. Each of those costs its own unit and
nothing else, and the units behind a failure are still produced - dropping
them would make the export look complete when it is not.

Consumers that relied on the exception keep their failure signal: ilspycmd
exits non-zero and lists the failures, the PowerShell cmdlets raise an error
record per failure, and the round-trip suite asserts the export reported none
- otherwise a crash on a method its own tests never call would ship green.
