Backport of #160366 to 3.15.
BOLT can change perf trampoline templates in executable sections and cause crashes. Store the ELF templates in .rodata, with the change in Python/asm_trampoline.S for this branch.
(cherry picked from commit 1ff83ad)

…nly data (pythonGH-160366)
CPython copies the trampoline templates into executable memory. Keep the
ELF source in .rodata so BOLT preserves its bytes and boundaries.
(cherry picked from commit 1ff83ad)
