Support the requirement where bootloader can be in chunks and enable
placing the application at a particular offset specified by config.
With FEATURE_BOOTLOADER support, the bootloader can be placed at a
high address. Add support to the tools so that application can be
placed in the available space before the beginning of the bootloader.
As per the IAR Development guide, below options for CPU are valid
1. Cortex-M33
2. Cortex-M33.no_dsp (core without integer DSP extension)
3. Cortex-M33.fp (floating-point unit with support for single precision)
4. Cortex-M33.no_se (core without support for TrustZone)
5. Cortex-M4
6. Cortex-M4F
7. Cortex-M7
8. Cortex-M7.fp.dp (floating-point unit with support for double precision)
9. Cortex-M7.fp.sp (floating-point unit with support for single precision)
Below are the options read from the toolchains/arm
armclang --target=arm-arm-none-eabi -mcpu=list
The following arguments to option 'mcpu' can be selected:
-mcpu=cortex-m0
-mcpu=cortex-m0plus
-mcpu=cortex-m1
-mcpu=cortex-m3
-mcpu=cortex-m4
-mcpu=cortex-m7
-mcpu=cortex-m23
-mcpu=cortex-m33
...
armlink --cpu=list
The following arguments to option 'cpu' can be selected:
--cpu=Cortex-M0
--cpu=Cortex-M0plus
--cpu=Cortex-M1
--cpu=Cortex-M1.os_extension
--cpu=Cortex-M1.no_os_extension
--cpu=Cortex-M4
--cpu=Cortex-M4.no_fp
--cpu=Cortex-M7
--cpu=Cortex-M7.fp.sp
--cpu=Cortex-M7.no_fp
--cpu=Cortex-M23
--cpu=Cortex-M33
--cpu=Cortex-M33.no_fp
--cpu=Cortex-M33.no_dsp
--cpu=Cortex-M33.no_dsp.no_fp
...
armclang --target=arm-arm-none-eabi -mfpu=list
The following arguments to option 'mfpu' can be selected:
-mfpu=fpv4-sp-d16
-mfpu=fpv5-sp-d16
-mfpu=fpv5-d16
...
For binary compatibility with ARMC5, use the hard ABI variant whenever
we have FP hardware - this is ARMC5's default behaviour, which we do not
override.
Cortex-M4F was already using hard; this brings M7F and M33F into line.
### Description
PR #8607 will cause problems for the NRF52832 and the NRF52840
in the online compiler starting with 5.10.2. This PR prevents this problem
by using a toggle in `targets.json` to enable these new defines for every
target except for the NRF52832 and NRF52840.

### Description
This PR moves the old memap file handling required for differential
memap from within memap to the toolchain object. This has the
advantage that we can do the `mv <app>.map <app>.map.old` the moment
before it is overwritten by the linker. This should allow multiple
reruns of memap without modifying your build directory.

The 'archive' method of the toolchain class 'ARM' expects that self.ar
is a string, but the constructor of the class 'ARMC6' initializes it
with a list. This patch fixes the issue.
