soc: allow creating SoC without BIOS.
...
By default the behaviour is unchanged and the SoC will provide a ROM:
./arty.py
Bus Regions: (4)
rom : Origin: 0x00000000, Size: 0x00008000, Mode: R, Cached: True Linker: False
sram : Origin: 0x01000000, Size: 0x00001000, Mode: RW, Cached: True Linker: False
main_ram : Origin: 0x40000000, Size: 0x10000000, Mode: RW, Cached: True Linker: False
csr : Origin: 0x82000000, Size: 0x00010000, Mode: RW, Cached: False Linker: False
The integrated rom can be disabled with:
./arty.py --integrated-rom-size=0
but the SoC builder will check for a user provided rom, and if not provided will complains:
ERROR:SoC:CPU needs rom Region to be defined as Bus or Linker Region.
When a rom is provided, the CPU will use the rom base address as cpu_reset_address.
If the user just wants the CPU to start at a specified address without providing a rom,
the cpu_reset_address parameter can be used:
./arty.py --integrated-rom-size=0 --cpu-reset-address=0x01000000
If the provided reset address is not located in any defined Region, an error will
be produced:
ERROR:SoC:CPU needs reset address 0x00000000 to be in a defined Region.
When no rom is provided, the builder will not build the BIOS.

This allows generating SVD export files during the build as we are already doing for .csv or .json.
Use with Builder:
builder = Builder(soc, csr_svd="csr.svd")
Use with target:
./arty.py --csr-svd=csr.svd

build: assume vendor tools are in the PATH and remove automatic sourcing, source and toolchain_path parameters.
...
Automatic sourcing was not consistent between build backends (and only really supported by ISE/Vivado)
and had no real additional value vs the complexity needed to support it. Now just assume required vendor
tools are in the PATH.
This also removes distutils dependency.
