fixes#22523
There were 2 problems with the code in `sameType` for
`dcEqIgnoreDistinct`:
1. The code that skipped `{tyDistinct, tyGenericInst}` only ran if the
given types had different kinds. This is fixed by always performing this
skip.
2. The code block below that checks if `tyGenericInst`s have different
values still ran for `dcEqIgnoreDistinct` since it checks if the given
types are generic insts, not the skipped types (and also only the 1st
given type). This is fixed by only invoking this block for `dcEq`;
`dcEqOrDistinctOf` (which is unused) also skips the first given type.
Arguably there is another issue here that `skipGenericAlias` only ever
skips 1 type.
These combined fix the issue (`T` is `GenericInst(V, 1, distinct int)`
and `D[0]` is `GenericInst(D, 0, distinct int)`).
#24037 shouldn't be a dependency but the diff follows it.
* clean up some test categories
* mention exact slice issue
* magics into system
* move trangechecks into overflow
* move tmemory to system
* try fix CI
* try fix CI
* final CI fix
* SameTypeAux now properly traverses generic distincts
* Smarter traversal of distincts
* Removed redundant check
* Fixed nkConv for jsgen
* Added test for non distinct nkConv
* using skiptypes for distinct now
* Fixed genaddr for nkconv
Make `requiresInit` pragma to work for distinct types in addition to
objects. Tagging of distinct types with `requiresInit` pragma was
already supported, but its impact wasn't applied. Now its behavior when
applied on distinct types is as follows.
Given the following distinct type definitions:
```nim
type
DistinctObject {.requiresInit, borrow: `.`.} = distinct MyObject
DistinctString {.requiresInit.} = distinct string
```
The following code blocks will fail to compile:
```nim
var foo: DistinctFoo
foo.x = "test"
doAssert foo.x == "test"
```
```nim
var s: DistinctString
s = "test"
doAssert s == "test"
```
But these ones will compile successfully:
```nim
let foo = DistinctFoo(Foo(x: "test"))
doAssert foo.x == "test"
```
```nim
let s = "test"
doAssert s == "test"
```
