f2fs: use BIT_ULL for mount option bitmasks

Although f2fs_mount_info.opt and f2fs_fs_context.opt_mask are declared as
unsigned long long (64 bits), the option bit manipulation macros
(clear_opt, set_opt, test_opt) and context helpers (ctx_set_opt,
ctx_clear_opt, ctx_test_opt) use BIT(), which expands to (UL(1) << nr).

On 32-bit architectures, sizeof(unsigned long) is 32 bits, causing shift
count overflow warnings and functional truncation if mount option indices
reach or exceed 32.

Replace BIT() with BIT_ULL() for mount option bitmasks and helpers.
Additionally, introduce ctx_clear_opt_mask() and ctx_test_opt_mask()
helpers to avoid open-coded bitwise manipulations on ctx->opt_mask.
