Fix return type encoding for ptrcall.

[bruvzg]

Fixes return and temporary variable types used for ptrcall according to conversions defined here:

godot-cpp/include/godot_cpp/core/method_ptrcall.hpp

Lines 116 to 127 in 7fa81e7

	MAKE_PTRARGCONV(bool, uint8_t);
	// Integer types.
	MAKE_PTRARGCONV(uint8_t, int64_t);
	MAKE_PTRARGCONV(int8_t, int64_t);
	MAKE_PTRARGCONV(uint16_t, int64_t);
	MAKE_PTRARGCONV(int16_t, int64_t);
	MAKE_PTRARGCONV(uint32_t, int64_t);
	MAKE_PTRARGCONV(int32_t, int64_t);
	MAKE_PTRARG(int64_t);
	MAKE_PTRARG(uint64_t);
	// Float types
	MAKE_PTRARGCONV(float, double);

Prevents stack corruption in the methods like int Node::get_child_count(bool p_include_internal) const, which are using 32-bit int return.

DownloadString('https://get.scoop.sh/') in the windows CI seems to be randomly failing.

DownloadString('https://get.scoop.sh/') in the windows CI seems to be randomly failing.

It seems to be a change in the script at https://get.scoop.sh, it wants us to set -RunAsAdmin:

# Detect if RunAsAdministrator, there is no need to run as administrator when installing Scoop.
    if (!$RunAsAdmin -and (Test-IsAdministrator)) {
        Deny-Install "Running the installer as administrator is disabled by default, use -RunAsAdmin parameter if you know what you are doing."
    }

Testing a potential fix in #722

It downloaded it successfully in the Windows (x86_64, MSVC) task, and my other PR failed once, but worked after I have restarted it, so it might be something else.

Rebasing on #723 should fix the CI.
