0e8a2999bd gowin: Add partnumbers and packages to the chipdb 
Instead of parsing the partnumber with a regular expression,
a simple table is used. This is done because the structure
of the partnumber changes as new features appear (e.g., ES instead of C6/I5)

This commit does not yet disable the very first regular expression check.

f52fd6a272 gowin: Add ALU support. 
- Both the mode used by yosys and all Gowin primitive modes are supported.
  - The ALU always starts with a zero slice.
  - The maximum length of the ALU chain is limited to one line of the chip.
