### Description
I noticed that there was quite a bit missing from the mbed2 release of
the microbit today. That's because the microbit uses ARM by default and
the GCC_ARM small library. The release script was trying to release for
ARM using scan rules for uARM. Turns out we're stuck with 2 configuration
parameters for the same thing: `default_lib` for GCC and `default_toolchain`
for ARM. Dang

### Description
2 calls to `notify.cc_verbose` used the a FileRef object in place of
the file's name. Other calls to `notify.cc_info` would use just the
file name. This PR changes these 2 calls to be consistant with the rest.

IAR assembler 7.80 has some problems handling difficult macros, leading
to immediate exit with return value -11.
In particular, a URL string has been causing problems, presumably due to
the "//" resembling a comment.
A previous escaping workaround in 0d97803 seemed to work, but the crash
has still been seen with a particular target.
Previous creation of the extended command line file for the IAR
assembler was stripping quotes from macros. This rendered the resulting
definitions for string-containing macros incorrect, which means that we
can assume no assembler code is currently relying on them.
Therefore, as a precautionary measure to avoid the crash, simply remove
all macros containing strings when creating them for IAR. This
apparently clears the crashes seen during testing of

Add the target config option "boot-stack-size" which is passed to the
linker as the define "MBED_BOOT_STACK_SIZE" so the linker can
adjust the stack accordingly. On mbed 2 the boot stack becomes the
main stack after boot. On mbed 5 the boot stack becomes the
ISR stack after boot. Because of these different uses the stack size
for mbed 2 is set to 4K by default while on mbed 5 it is set to 1k.
Additionally, the NRF5X family requires a larger interrupt stack size
due to the softdevice so the size is increased to 2k on mbed 5 builds.
-mcpu option if set for v8M CPU;s it will add DSP feature as default
which is optional. Hence setting just the architecture for Cortex-M23
and Cortex-M33
".cc" --> C++ source code
".hh" --> header
This change allows existing source code with this naming
convention (e.g. my company's) to be used in mbed.os projects.
