std.ArrayList: mark the appendNTimes methods inline
The previous commit introduced an optimization to the LLVM backend that
makes `@memset` lower more optimally when the element is comptime-known
and has a repeating byte pattern.
By making these functions inline, if the element parameter is
comptime-known at the callsite, it will be comptime-known in the
`@memset` call, causing more use of the LLVM `memset` intrinsic rather
than an inline for loop when using the LLVM backend.
This affects, for example, std.crypto.argon2, which calls
appendNTimesAssumeCapacity with a `[128]u64` as the element. This is now
lowered with a single `memset` call.
