  [libc][arm32] define argc type and stack alignment (#96367)

https://github.com/ARM-software/abi-aa/blob/main/aapcs32/aapcs32.rst#6212stack-constraints-at-a-public-interface
mentions that the stack on ARM32 is double word aligned.

Remove confused comments around ArgcType. argc is always an int, passed on the
stack, so we need to store a pointer to it (regardless of ILP32 or LP64).
