Remove duplicate #include statements

[khaledalam]

Description

Remove 26 duplicate #include statements from 21 files across the codebase.

Motivation

• Improves code clarity by removing visual noise
• Makes dependency graphs cleaner for static analysis tools
• Aligns with coding standards for maintainable code

Compile-Time Impact

Removes 26 redundant file lookups and preprocessor guard evaluations during compilation.

Changes

Directory	Files Modified
Zend/	3
main/	2
sapi/	10
ext/	6

Notable duplicates removed:

• php.h, php_globals.h in SAPI files
• zend_vm_opcodes.h in zend_compile.h
• http_core.h in apache2handler (3 files)
• <sys/types.h> in multiple wrappers

Notes

• All removed includes were true duplicates (unconditional, same file)
• Excludes intentional duplicates in #if/#elif branches
• No functional changes - include guards already prevented reprocessing

Thanks @DanielEScherzer for the feedback, yes I were try to be careful about exclude conditional ones but i missed that file.
