GN: Fix the Mac build (project-chip#2102)

* GN: Fix the Mac build

* Enable more debug printing in Silicon Labs code (project-chip#2087)

* [nrf5] Repair the newlib locking (project-chip#2100)

* [nrf5] Repair the newlib locking

Calling stdio functions in certain circumstances currently crashes the
device. Enabling configUSE_LIST_DATA_INTEGRITY_CHECK_BYTES makes this
more likely to happen.

The problem is that the types used in FreeRTOSNewlibLockSupport.c don't
match those used by newlib; we're mixing up struct __lock * with its
content.

Fix the implementation and remove all the typecasts. Note that we need a
2nd allocation for the dynamic case as FreeRTOS and newlib APIs don't
match up well.

Possibly we should remove this code, but for now just repair it.

fixes project-chip#2084

* Add include paths to automake

* Sync pigweed & fix build resulting build errors
