  [clang] Add support for new loop attribute [[clang::code_align()]] (#70762)

This patch adds support for new loop attribute:
[[clang::code_align(N)]].
This attribute applies to a loop and specifies the byte alignment for a
loop.
The attribute accepts a positive integer constant initialization
expression
indicating the number of bytes for the minimum alignment boundary.
Its value must be a power of 2, between 1 and 4096 (inclusive).
