To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.
Currently up_allocate_heap() assumes that g_idle_topstack points
top of the heap memory. However, g_idle_topstack pointed incorrect
address in SMP mode which resulted in heap corruption. This PR
moves g_idle_topstack at the end of .noinit to avoid this issue.

This commit does two things:
1. First, it reorganizes the driver Kconfig files so that each is self contained. Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig. Now, all of the driver configuration is consolitated in the latter.
2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files. This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well.
The nature of the introduced error was basically this:
- Nothing must intervene between the menuconfig selection and the following conditional configuration otpions.
- A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus.
This error was easy to make because the driver Kconfig files were not well modularized. Making them fully self-contained should eliminate this kind of error in the future.
The benefit include:
1. Simplify the implementation
2. Support both tick and tickless automatically
3. No time drift in tickless mode
4. Support critmon arch API automatically
Basically a copy-and-paste from spresense.
But I added -mlong-calls for ELF to avoid out of range relocations.
(Isn't it necessary for spresense?)
