[PATCH 0/4] MR4761: ntdll: Implement NtContinueEx()

[Dāvis Mosāns]

This MR implements `NtContinueEx(PCONTEXT, PCONTINUE_OPTIONS)` which was added in Windows 10 20H1.

Also added basic test reusing existing `test_continue()` (included from !4720)

League of Legends game hooks `NtContinue()` and `NtContinueEx()` by putting `jmp` instruction in front of it.

Note that LoL doesn't actually use `NtContinueEx()` itself and game will work fine without it but if game doesn't find `NtContinueEx()` it will permanently ban your account due to detecting "scripting program"
