[Go] Scope the built-in functions clear, max and min

[yu2971512385-ui]

predeclared_func lists Go's built-in functions up to Go 1.20. Go 1.21 added three more — clear, max and min — so calls to them are scoped as ordinary functions while append, len, delete and the rest get support.function.builtin.go:

    clear(m)   // variable.function.go        (before)
    close(c)   // variable.function.go support.function.builtin.go

predeclared_type is already current for Go 1.18 (it has any and comparable), so this just brings the function list to the same version of the language.

Since the rule only matches a predeclared name that is directly followed by a call's (, shadowed uses such as min := 0 or var max int keep their ordinary scope, exactly as for the names already in the list.

Syntax tests were added under "Other Functions" alongside the existing close cases (including a bare min to check the call-only behaviour). I could not run Sublime's syntax test runner locally, so the assertions mirror the existing close(ident) block exactly and I verified the caret columns line up with the code above them; CI will confirm.

AI assistance (Claude) was used to find this gap — by lexing modern Go and looking for predeclared identifiers that stay unscoped — and to draft this description. I reviewed every line.
