Adds a new hook before static memory initialization occurs, namely
initialization of .bss and .data, which is frequently used for
things like enabling other memory regions with .data and/or .bss
sections.
The FPU enabling for targets/stm32f429i-disc1/early_boot.c was moved
to pw_boot_PreStaticMemoryInit(), as this is may be needed for
other pre static memory initialization tasks.
In addition, the existing pw_boot_armv7m module is updated to follow
the new naming style guide to prefix globals with "pw_boot_*".
And lastly, the documentation is extended slightly to further explain
what each hook is typically used for.
