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.

software/bios/sdram: allow setting CLK/CMD delay from user design and configure it before write/read leveling.
...
Setting a manual delay on CLK/CMD vs DQ/DQS is required on some configuration to center the write leveling window:
Before (delay = 0 taps):
Write leveling:
m0: |11000000000000011111111111| delay: 15
m1: |00000000000000111111111111| delay: 14
m2: |11110000000000000111111111| delay: 17
m3: |11110000000000000011111111| delay: 18
m4: |11111111110000000000000111| delay: 00
m5: |11111111110000000000000111| delay: 00
m6: |11111111111000000000000001| delay: 00
m7: |11111111111000000000000011| delay: 00
After (delay = 12 taps):
Write leveling:
m0: |11111111111111000000000000| delay: 00
m1: |11111111111100000000000001| delay: 00
m2: |00011111111111110000000000| delay: 03
m3: |00011111111111110000000000| delay: 03
m4: |00000000111111111111110000| delay: 08
m5: |00000000111111111111110000| delay: 08
m6: |00000000001111111111111000| delay: 10
m7: |00000000001111111111111000| delay: 10
