Like __call trampolines, we can use an opcode-based trampoline to reduce recursion/reentering, and reuse the call frame of the trampoline. Also: Rebase fixes, update tests, add tests.

This would be nice to do, but that would require allocating zend_strings rather than using C strings which are inside the binary. Would make a lot of other stuff simpler tho.

It looks like we still need a test for partially applying an invokable object that isn't a Closure. |

Based on php#6898.
With the following changes:
trampolineis now a user function. This avoids re-entering the VM, and allows to re-use the trampoline stack frame when calling the real function. This is similar to__calltrampolines.trampolineandprototypeare merged into a singlezend_function. This simplifies a few things and speeds up PFA creation a bit.ZEND_ACC_andZEND_CALL_flags since there are no free slots anymorenewis not allowedStill a WIP. There are a few things to check and cleanup.
