85ce118386 fixes #26123; Update PathKinds1 to include nkCast (#26126)
fixes #26123

`cast[T](x)` is a transparent path expression for compiler analysis.
Previously, move/alias analysis could fail to see a later use through a
cast and incorrectly mark the source as moved, causing the issue’s
segmentation fault.

for views,
https://nim-lang.org/docs/manual_experimental.html#view-types-path-expressions:
A cast expression cast[T](e) is a path expression.

It also affects skipConvDfa, isAnalysableFieldAccess, and aliases. And I
might narrow it down for the two cases above mentioned if it causes
problems
