switch all .S files to unified asm, and use a macro to setup compiler and some other misc changes (#1295)

Browse Source 
* switch all .S files to unified asm, and use a new macro `pico_default_asm_setup` to setup compiler to help porting to other compilers. Also some minor tweaks:
* switch some code to use more recent helper methods (e.g. busy_wait_at_least_n_cycles)
* add documentation to host divider header (I had this ages ago and never promoted)
* fixup erroneous docs about 32p32 values in all divider headers
* fix some compiler warnings
* rename recently added `unified_asm` macro to `pico_default_asm`
