Unit tests: Move target_h/ stubs into libraries' test doubles

Travis: Enable maximum verbosity of pinvalidate.py ...

Run pinvalidate.py with -vvv to print the cause of failure, making
it easier for authors of pull requests to fix pin names.

Unit tests: Fix pin validation failure ...

The test script pinvalidate.py requires the following which are
missing in the unit test stub PinName.h:
* A comment "MBED TARGET LIST"
* `CONSOLE_TX` and `CONSOLE_RX` in the `PinName` enum

This commit adds them.

Unit tests: Remove redundant CMake target mbed-headers-base ...

Individual libraries' `target_h` stub headers have now all been moved
from `mbed-headers-base` to `mbed-headers-<library>`.

Note: Even though headers previously in `target_h` are technically
stubs/fakes too, they are used by not only unit tests but also regular
libraries when compiled for unit tests, because no target-specific HAL
implementation exists in this case. In order for regular library
sources to pick up `target_h` headers, those headers must

* have the same names as regular headers
* appear first in include paths

This is why those headers are part of `mbed-headers-<library>` and not
`mbed-stubs-<library>`. Before this refactoring, `mbed-headers-base`
was the first in unit tests' include paths.

Unit tests: Fix style in hal gpio_object.h stub

Unit tests: Move hal target_h stubs ...

Stubs previously in UNITTESTS/target_h/ have the same names as
regular Mbed OS headers, intending to override the latter directly.
We move hal target_h stubs into hal/tests/UNITTESTS/doubles/.

Note: In Mbed OS, the standard include format requires each header to
be prefixed with its module name, for example "hal/gpio_api.h". This
requires headers to be organized in a module directory. But unit tests
stubs for hal correspond to what a real Mbed target would have
implemented (in a non-test scenario), and targets do not currently put
headers in hal/, so we similary put stub headers directly in
hal/tests/UNITTESTS/doubles/ instead of add a hal/ subdirectory there.

Unit tests: Move randLIB.h ...

The stub header randLIB.h overrides the header of the same name in
platform/randlib/ which is an external repository vendored into
the mbed-os codebase. As the repository is synchronized regularly,
it is better not to put overrides there, so we put the randLIB.h
stub into the regular platform doubles directory.

Unit tests: Move drivers target_h stubs

Unit tests: Fix style in rtos Thread.h stubs

Unit tests: Move rtos target_h stubs

Unit tests: Remove mbed.h stub from target_h ...

The header `mbed.h` is a convenient wrapper that pre-includes some
platform headers, for use by user applications. Libraries and tests
internal to Mbed OS should not use it, and they should explicitly
include headers they need. So a stub is not needed.

Unit tests: Move platform target_h stubs ...

Stubs previously in UNITTESTS/target_h/ have the same names as
regular Mbed OS headers, intending to override the latter directly.
We move platform target_h stubs into
platform/tests/UNITTESTS/doubles/platform/.

Note: nvic_wrapper.h is normally implemented and used by Mbed targets
as needed. But as unit tests do not have a real target, we treat it
as a stub for the platform.

Unit tests: Move cmsis target_h stubs ...

This creates a new mbed-headers-cmsis which is always and only used
by mbed-headers-platform, so we add the former to the laters' linked
targets.

Unit tests: Fix style in cellular myCellularContext.h stub

Unit tests: Move cellular target_h stubs ...

We move test-specific files from the top-level UNITTESTS directory
into individual components' UNITTESTS/doubles subdirectories.

Unit tests: Remove unused syslimits.h

Unit tests: Remove unused nsapi_ppp.h stub

Unit tests: Remove unused arm_math.h

rtos: fix delay with 0 ...

Fixes error osErrorParameter that triggers our assert.
RTX delay ignored 0 previously, it now returns osErrorParameter instead.

cmsis: patch fpu in asm for armcc5 ...

For FPU, use armasm to select fpu selection. This will be fixed upstream in the next version of CMSIS. Meanwhile, we use our local patch.

Taken from --cpu selection for armasm:

--cpu           | {FPU}
Cortex-M4.fp.sp | VFPv4_SP_D16
Cortex-M7.fp.sp | FPv5-SP
Cortex-M7.fp.dp | FPv5_D16
