Nuvoton: Enlarge NuMaker PWM duty cycle range

To keep proprietary BSP DutyCycle definition and rename HighDutyCycle in extend API

Remove uARM dependencies from Nuvoton targets

Support M251/M261/M453/NANO130/NUC472 PWM duty cycle range as 0 ~ 10000

Nuvoton: Remove DISABLE/ENABLE macro definitions in BSP ...

These are not used on Mbed OS. Remove them to avoid name conflict with other modules.

CMake nuvoton: fix ARMClang linker script command

stack: armc: Workaround config passing bug ...

Workaround a bug where the boot stack size configuration option is not
passed on to armlink, the Arm Compiler's linker. Prefer
MBED_CONF_TARGET_BOOT_STACK_SIZE if present, as this is what the
configuration system should provide. Fall back to MBED_BOOT_STACK_SIZE
if MBED_CONF_TARGET_BOOT_STACK_SIZE is not defined, as in the case of
buggy tools. If both MBED_CONF_TARGET_BOOT_STACK_SIZE and
MBED_BOOT_STACK_SIZE are not defined, then we fall back to a hard-coded
value provided by the linkerscript. See
https://github.com/ARMmbed/mbed-os/issues/13474 for more information.

Use boot stack size from config system ...

To allow overriding of the boot stack size from the Mbed configuration
system, consistently use MBED_CONF_TARGET_BOOT_STACK_SIZE rather than
MBED_BOOT_STACK_SIZE.

Fix nuc472 SD buffer alignment

NUMAKER_PFM_NUC472: keep __vector_handlers symbol in LTO builds ...

Add a "used" attribute to __vector_handlers to fix ARMC6 build with
the "-flto" flag.
(Error: L6236E: No section matches selector - no section to be FIRST/LAST.)

This attribute, attached to a function/variable, means that code must be emitted
for the function even if it appears that the function is not referenced.

Nuvoton: Support dynamic heap configuration on IAR ...

On IAR, configure heap to 1KiB at a minimum and expandable, dependent on available SRAM. This requires IAR 8.x.

Support targets:
-   NUMAKER_PFM_NUC472 w/ and w/o XRAM
-   NUMAKER_PFM_M453
-   NUMAKER_PFM_M487/NUMAKER_IOT_M487
-   NUMAKER_IOT_M263A
-   NUMAKER_M252KG

Target_NUVOTON: Add ARM_LIB_STACK and ARM_LIB_HEAP section ...

Instead of user defined symbols in assembly files or C files,
use linker scripts to add heap and stack - this is inconsistent
with ARM std linker scripts

Nuvoton: Fix alignment of execute region to 8-byte boundary ...

--legacyalign, --no_legacyalign are deprecated from ARMC6 compiler, in order to
remove deprecated flags all linker files (GCC and IAR as well to have uniformity)
should strictly align to 8-byte boundary
