  [CIR] Raise IntType max bitwidth to match LLVM IR (#191499)

Follow-up to #188113 per @erichkeane's feedback about the 128-bit cap.

CIR's IntType was hard-limited to 128 bits, which meant any _BitInt
wider than that hit an errorNYI. LLVM IR goes up to 2^23 (about 8
million bits), and there are real tests/users at those sizes. This
raises CIR's limit to match and drops the guard that was working around
it.

Tests: added a _BitInt(256) global to bitint.c and a 1024-bit round-trip
to bitint.cir.
