Change gdbarch_wchar_bit for AArch64 and ARM
The size of wchar_t on AArch64 and ARM is 4-byte, so we can use the
default value (4*TARGET_CHAR_BIT).
This patch fixes some fails in gdb.cp/wide_char_types.exp on
aarch64-linux.

* aarch64-tdep.c (aarch64_gdbarch_init): Don't call
set_gdbarch_wchar_bit.
* arm-tdep.c (arm_gdbarch_init): Likewise.
