  [compiler-rt][ubsan][nfc-ish] Fix a type conversion bug (#100665)

If the inline asm version of `ptrauth_strip` is used instead of the
builtin, the inline asm implementation currently returns an unsigned
long, causing an incompatible pointer conversion issue. The spec for
`ptrauth_sign` is that the result has the same type as the original
value, so we add a cast to the result of the inline asm.

(cherry picked from commit 25f9415713f9f57760a5322876906dc11385ef8e)
