fixes#23742
Before my PR, `setLen(0)` doesn't free buffer if `s != nil`, but it
allocated unnecessary memory for `strs`. This PR rectifies this
behavior. `setLen(0)` no longer allocates memory for uninitialized
strs/seqs

Since #23188 the compiler errors when matching a type variable to an
uninstantiated static value. However sometimes an uninstantiated static
value is given even when only a type match is being performed to the
base type of the static type, in the given issue this case is:
```nim
proc foo[T: SomeInteger](x: T): int = int(x)
proc bar(x: static int): array[foo(x), int] = discard
discard bar(123)
```
To deal with this issue we only error when matching against a type
variable constrained to `static`.
Not sure if the `q.typ.kind == tyGenericParam and
q.typ.genericConstraint == tyStatic` check is necessary, the code above
for deciding whether the variable becomes `skConst` doesn't use it.

```nim
dest.`:state` = src.`:state`
var :tmp_553651276 = dest.e1.a
`=wasMoved`(dest.e1.a)
dest.e1.a.kind = src.e1.a.kind
case dest.e1.a.kind
of 0:
dest.e1.a.a = src.e1.a.a
of 1:
`=copy`(dest.e1.a.c, src.e1.a.c)
case :tmp_553651276.kind
of 0:
of 1:
`=destroy`(:tmp_553651276.c)
```
`dest.e1.a.kind = src.e1.a.kind` changes the discrimant but it fails to
clear the memory of `dest.e1.a`. Before using hooks for copying, we need
to clear the dest, e.g. `=wasMoved(dest.e1.a.c)`.
```nim
dest.`:state` = src.`:state`
var :tmp_553651276 = dest.e1.a
`=wasMoved`(dest.e1.a)
dest.e1.a.kind = src.e1.a.kind
case dest.e1.a.kind
of 0:
`=wasMoved`(dest.e1.a.a)
dest.e1.a.a = src.e1.a.a
`=wasMoved`(dest.e1.a.b)
of 1:
`=wasMoved`(dest.e1.a.c)
`=copy`(dest.e1.a.c, src.e1.a.c)
case :tmp_553651276.kind
of 0:
of 1:
`=destroy`(:tmp_553651276.c)
```

I could trivially port Nim to NetBSD/aarch64 because it already
supported NetBSD and aarch64. I only needed to generate `c_code` for
this combination.

This adds a version of `almostEqual` (which was already available for
floats) thata works with `Complex[SomeFloat]`.
Proof that this is needed is that the first thing that the complex.nim
runnable examples block did before this commit was define (an
incomplete) `almostEqual` function that worked with complex values.

`void` is only supported as fields of objects/tuples. It shouldn't allow
void in the array.
I didn't merge it with taField because that flag is also used for
tyLent, which is allowed in the fields of other types.

fixes#23321
In the function `mapType`, ptrs (tyPtr, tyVar, tyLent, tyRef)
are mapped into ctPtrToArray, the dereference of which is skipped
in the `genref`. We need to skip these ptrs in the function
`genOpenArraySlice`.

Previously, in certain cases, the compiler would generate debug info for
the correct line number, but for the wrong .nim source file.

This solution should resolve the nimsuggest crash issue. However,
perhaps the problem is in the parser?
