[Zend]: Fix unnecessary alignment in ZEND_CALL_FRAME_SLOT macro (#10988)

Alignment is not necessary while calculating slots reserved for
zend_execute_data and _zend_vm_stack.

ZEND_STATIC_ASSERT ensures the correct alignment while code
compilation. Credit is to Ilija Tovilo.

Add IBT support for fiber

Indirect Branch Tracking (IBT) is part of Intel's Control-Flow
Enforcement Technology (CET). IBT is hardware based, forward edge
Control-Flow-Integrity mechanism where any indirect CALL/JMP must target
an ENDBR instruction or suffer #CP.

This commit adds IBT support for fiber:
1. Add endbr32/64 in assembly
2. Inform compiler jump_fcontext may return via indirect branch

Furthermore:
gcc support CET since v8.1 and set it to default since gcc 11. That is,
the ELF header of sapi/cli/php has a property named IBT. However, such
property is lost since PHP8.1 because the assembly introduced by Fiber.
This commit also fixes this.

Suppress unused label warnings in SWITCH VM

While we avoid emitting labels for handlers that are not referenced
from anywhere else, we do not perform a fine-grained analysis on
used specializations, so some of the specialization labels may not

"cold" from the definition of this attribute, as it is completely
