[SelectionDAG][VP] Add splitting/widening for VP_LOAD and VP_STORE

Original patch by @hussainjk.

This patch was split off from D109377 to keep vector legalization
(widening/splitting) separate from vector element legalization

While the original patch added a third overload of
SelectionDAG::getVPStore, this patch takes the liberty of collapsing
those all down to 1, as three overloads seems excessive for a
little-used node.

The original patch also used ModifyToType in places, but that method
still crashes on scalable vector types. Seeing as the other VP
legalization methods only work when all operands need identical
widening, this patch follows in that vein.

[lldb] Remove anon struct from frame-var-anon-unions test

This test for anonymous unions seems off. It tests the following:

union {
  // fields

struct {
  // fields
} var{...};

Both are anonymous types, but the first does not declare a variable and the
second one does. The test then checks that `frame var` can directly access the
fields of the anonymous union, but can't directly access the fields of the
anonymous struct variable.

The second test, to directly access the members of the struct variable, seems
pointless as similar code would not compile. A demonstration:

struct {
  int a;
  int z;
} a_z{23, 45};

printf("%d\n", a_z.a); // fine
printf("%d\n", a); // this does not compile

Since we can't directly access the fields in code, I'm not sure there's a
reason to test that lldb also can't directly access them (other than perhaps as
a regression test).

Anecdotally this reduces the number of static library built when the
builtin target is disabled goes from 236 to 218.

Ensure that errors in `frame variable` are reflected in result object.

The statistics for `frame variable` show invocations as being successful, even

This change replaces `result.GetErrorStream()` with `result.AppendError()`,
