arm: Avoid call k[u]mm_memalign to save the code size
ceva: Correct stack_base_ptr usage(top of stack v.s. bottom of stack)
mips: Correct the stack alignment in up_use_stack
misoc: Correct the stack alignment in up_use_stack
or1k: Correct the stack alignment in up_use_stack

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
Some toolchains may be built without libm support, but using
such toochain should not generate any errors in case if math
functions are not used in the program

For example, task is blocked by nxsem_wait(sem1), use nxsem_wait(sem2)
in signal handler, and take sem2 successfully, after exit from signal
handler to task, nxsem_wait(sem1) returns OK, but the correct result
should be -EINTR.

This reverts commit 45672c269d.
Because:
* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
supposed to do when we use LD directly. It would be simpler to
remove them from our LDFLAGS.

Cleaning during `clean_context` had the issue of remaking everything
when `menuconfig` was issued. That's because `menuconfig` has a
`clean_context` on its way.

instead calling kmm_heapmember or umm_heapmember because:
1.The stack supplied by caller may allocate from heap too
2.It's hard to implement these two function in ASan case

All modern desgin support stack pointer and it's also an
important information, so let's standardize this interface.

arch: Allocate the space from the beginning in up_stack_frame
and modify the affected portion:
1.Correct the stack dump and check
2.Allocate tls_info_s by up_stack_frame too
3.Move the stack fork allocation from arch to sched

All supported arch uses a push-down stack:
The stack grows toward lower addresses in memory. The stack pointer
register points to the lowest, valid working address (the "top" of
the stack). Items on the stack are referenced as positive(include zero)
word offsets from sp.
Which means that for stack in the [begin, begin + size):
1.The initial SP point to begin + size
2.push equals sub and then store
3.pop equals load and then add
