Pybind11: add v2.11.1

@waruqi pybind 11 构建测试时，所有的报错都发生在 Windows x86 和 Arm64 上。

x86 构建里报错是Python config failure: Python is 64-bit, chosen compiler is 32-bit，已经正常安装 x86 Python 3.11 但找到的是 x64 Python 3.9。

Windows Arm64 构建里的报错是fatal error C1083: Cannot open include file: 'Python.h': No such file or directory，已经正常安装 x64 Python 3.11 但是构建系统找不到。

会不会是 Python 环境注入发生了什么问题？我查看了 pybind11 的 FindPythonLibsNew.cmake 发现整体流程挺自然的

@waruqi When building tests with pybind 11, all errors occur on Windows x86 and Arm64.

The error reported in the x86 build is Python config failure: Python is 64-bit, chosen compiler is 32-bit. x86 Python 3.11 has been installed normally but x64 Python 3.9 is found.

The error reported in the Windows Arm64 build is fatal error C1083: Cannot open include file: 'Python.h': No such file or directory. x64 Python 3.11 has been installed normally but the build system cannot find it.

Could there be something wrong with Python environment injection? I checked FindPythonLibsNew.cmake of pybind11 and found that the overall process is quite natural.

调下 python 那个包的 on_fetch ，然后提 pr 改进下

我试试看吧，不知道 Qemu 模拟的 Windows arm64 够不够味

I'll give it a try, I don't know if the Windows arm64 simulated by Qemu is interesting enough.

目前已经发现是某些情况在这里没有正确找到out libpath includepath,

xmake-repo/packages/p/python/fetch.lua

Lines 56 to 64 in cebf559

	link = format("python" .. table.concat(table.slice(version:split("%."), 1, 2), ""))
	print("python program: " .. program .. ", version: " .. version .. ", link: " .. link .. ", exepath: " .. exepath)
	local out = try { function () return os.iorunv(program, { "-c", "import sys; print(sys.base_prefix, end='')" }) end }
	print("python base_prefix: " .. out)
	libpath = find_library(link, { exepath, out }, { suffixes = { "libs" } })
	print("python libpath: " .. libpath.link)
	linkdirs = {}
	includepath = find_path("Python.h", { exepath, out }, { suffixes = { "include" } })

其输出在 https://github.com/xmake-io/xmake-repo/actions/runs/7289700908/job/19864898317?pr=2976#step:5:377 可见

我无法在本地虚拟机里复现问题, 修改 print 在 CI 里看不到, 接下来就等有缘人了

It has been found that out libpath includepath is not found correctly here in some cases.

xmake-repo/packages/p/python/fetch.lua

I can't reproduce the problem in the local virtual machine. I can't see it in CI after modifying the print command. I'll have to wait for someone to do it next.
