critical: fix non valid configuration
...
If any architecture is added, needs to update critical exclusive access.
Also fixing if exclusive access is defined, we use the value.

critical: fix set exclusive access if not yet defined
...
Fixes #5555 bug.
In case there is not yet defined __EXCLUSIVE_ACCESS, neither MBED_EXCLUSIVE_ACCESS that
we are introducing, use architecture macros to find out if MBED_EXCLUSIVE_ACCESS can be
enabled.

Fix potential race condition in critical section HAL API
...
Call underlying HAL implementation to enter critical section/disable interrupts
before incrementing the global critical section counter.
Modify HAL implementations to track first entrances to the critical section and
only update the saved state on first enter.

Add Critical Section HAL API specification
...
- Define header functions for Critical Section HAL API
- hal_critical_section_enter()
- hal_critical_section_exit()
- Add weak default implementation for HAL API. The default implementation
matches the previous behaviour stored in mbed_critical:
- The first call to enter a critical section stores the state of interrupts
before disabling and each successive call re-disables interrupts.
- The last call (non-nested) will restore the IRQ state that was set on the
enter to the critical section. Nested calls are ignored.
- Add function 'core_util_in_critical_section' to User facing API to determine
if the program is currently in a critical section, instead of depending on
'core_util_interrupts_enabled'.

Make LDREX/STREX CAS functions strong
...
The LDREX/STREX implementations of the compare-and-swap functions were
weak (they could spuriously fail when the value was expected), whereas
the critial section implementation was strong, and the documentation has
no suggestion that there might be spurious failures.
Rationalise by adding a retry loop for STREX failure, so that it only
returns false when the value is not expected.

Fix non-portable defines
...
A define which expands to more defines is not portable across all
compilers and GCC warns about this. Restructure this so the behavior
is defined. This fixes the GCC warning:
"this use of "defined" may not be portable"
