* Windows: `Architecture` from `php -i`

php -i architecture is MSVC style X86 X64 and ARM64 not gnu sytle i386 x86_64 aarch64 or bsd style x86 x86_64 arm64

I've made an extension release using msvc style and pie cannot find that extension release.

So should we make it clear? like giving a mapping table

MSVC style	GNU style	BSD style	golang style	PIE using
X86	i?86	x86	386	???
X64	x86_64	x86_64	amd64	x86_64
ARM64	aarch64	arm64	arm64	???

for reference:

C:\php\84ts\php.exe -r 'var_dump(php_uname("m"));'
string(5) "AMD64"

C:\php\84ts\php.exe -i | findstr.exe 'Arch'
Architecture => x64
