The goal of this PR is to make `typeRel` accurate to it's definition for
generics:
```
# 3) When used with two type classes, it will check whether the types
# matching the first type class (aOrig) are a strict subset of the types matching
# the other (f). This allows us to compare the signatures of generic procs in
# order to give preferrence to the most specific one:
```
I don't want this PR to break any code, and I want to preserve all of
Nims current behaviors. I think that making this more accurate will help
serve as ground work for the future. It may not be possible to not break
anything but this is my attempt.
So that it is understood, this code was part of another PR (#22143) but
that problem statement only needed this change by extension. It's more
organized to split two problems into two PRs and this issue, being
non-breaking, should be a more immediate improvement.

`{.push overflowChecks: off.}` works in backends. Though it could be
implemented as a magic function.
By inspecting the generated C code, the overflow check is eliminated in
the debug or release mode.
Likewise, the index checking is probably not needed.

`semtempl` is refactored to combine the uses of `getIdentNode`,
`onlyReplaceParams`, `isTemplParam` and most of `replaceIdentBySym` into
a single `getIdentReplaceParams` proc. This might fix possible problems
with injections of `nkAccQuoted`.
Some special word comparison in `ast` and `semtempl` are also made more
efficient.

Close#21742
Checking if there's any side-effects and if just changing typeRel is
adequate for this issue before trying to look into related ones.
`skipBoth` is also not that great, it can lead to code that works
sometimes but fails when the proc is instantiated with branching
aliases. This is mostly an issue with error clarity though.

fixes#22639 for the third time
Nodes generated by `getType` for `tyGenericInst` types, instead of
having the original `tyGenericInst` type, will have the type of the last
child (due to the `mapTypeToAst` calls which set the type to the given
argument). This will cause subsequent `getType` calls to lose
information and think it's OK to use the sym of the instantiated type
rather than fully expand the generic instantiation.
To prevent this, update the type of the node from the `mapTypeToAst`
calls to the full generic instantiation type.

fixes#22598, properly fixes#21887 and fixes test case issue number
When an enum field sym choice has to choose a type, check if its name is
ambiguous in the local scope, then check if the first symbol found in
the local scope is the first symbol in the sym choice. If so, choose
that symbol. Otherwise, give an ambiguous identifier error.
The dependence on the local scope implies this will always give
ambiguity errors for unpicked enum symchoices from generics and
templates and macros from other scopes. We can change `not
isAmbiguous(...) and foundSym == first` to `not (isAmbiguous(...) and
foundSym == first)` to make it so they never give ambiguity errors, and
always pick the first symbol in the symchoice. I can do this if this is
preferred, but no code from CI seems affected.
