Fix GH-22849: error_include_args=1 mishandled for include()

[NattyNarwhal]

include and friends aren't functions, but constructs of the engine. Special-case them and snarf their argument for display.

Not sure if this is the best way to handle it (or if we'd also need to special-case other opcodes here too)

[Girgias]

I guess this is fine.

I was confused why this didn't work backtraces can include requires and includes, but I think the reason why fetching the arguments for include/require doesn't work via the backtrace is that zend_fetch_debug_backtrace() assumes it cannot be called during a require/include/eval "call" and so the first frame is never checked to be an opcode.

[NattyNarwhal]

Yeah, I noticed the special-casing as well with the inserting of fake frames, but it assumes it would never be the top frame.

[NattyNarwhal]

I think the other (maybe better?) approach would be to insert a top-level fake frame for include events, but the logic in zend_fetch_debug_backtrace is a little hairy to follow. I also don't think it would disrupt much, because the only situation it should trigger is this.
