**TODO**
- [x] fixes changelog
With the new option `nimPreviewVtables`, `methods` are confined in the
same module where the type of the first parameter is defined
- [x] make it opt in after CI checks its feasibility
## In the following-up PRs
- [ ] in the following PRs, refactor code into a more efficient one
- [ ] cpp needs special treatments since it cannot embed array in light
of the preceding limits: ref
https://github.com/nim-lang/Nim/pull/20977#discussion_r1035528927; we
can support cpp backends with vtable implementations later on the
comprise that uses indirect vtable access

refs #22605
Sym choice nodes are now only allowed to pass through semchecking if
contexts ask for them to (with `efAllowSymChoice`). Otherwise they are
resolved or treated as ambiguous. The contexts that can receive
symchoices in this PR are:
* Call operands and addresses and emulations of such, which will subject
them to overload resolution which will resolve them or fail.
* Type conversion operands only for routine symchoices for type
disambiguation syntax (like `(proc (x: int): int)(foo)`), which will
resolve them or fail.
* Proc parameter default values both at the declaration and during
generic instantiation, which undergo type narrowing and so will resolve
them or fail.
This means unless these contexts mess up sym choice nodes should never
leave the semchecking stage. This serves as a blueprint for future
improvements to intermediate symbol resolution.
Some tangential changes are also in this PR:
1. The `AmbiguousEnum` hint is removed, it was always disabled by
default and since #22606 it only started getting emitted after the
symchoice was soundly resolved.
2. Proc setter syntax (`a.b = c` becoming `` `b=`(a, c) ``) used to
fully type check the RHS before passing the transformed call node to
proc overloading. Now it just passes the original node directly so proc
overloading can deal with its typechecking.

* Windows: enable nimRawSetjmp by default
See #19197. The default setjmp can randomly segfault on windows
* Attempt to disable the flag for bootstraping
* Disable styleCheck for c_setjmp
This flag has a very significant performance impact on programs compiled with --threads:on. It is also apparently not needed anymore for standard circumstances. Can we remove the config? See https://github.com/nim-lang/Nim/issues/18146#issuecomment-876802676 for discussion and perf impact. [backport:1.6]
