gowin: Correct B_MINWIDTH for 27x17 
The 27x18 rule carried B_MINWIDTH=13, so any product whose narrower operand
was below 13 (e.g. 27x4, 4x13) was rejected even though it fits one
MULTALU27X18 tile, and decomposed onto MULT12X12 partials instead. Drop the
floor to 2 so the rule blocks only degenerate Nx1 multiplies, matching the
rest of the tree.

Adds a 4x13 regression case.

mul2dsp: normalize operand order 
Move the operand commute that puts the wider operand on A ahead of the
min-width checks. Checking the min-widths first made an asymmetric rule
(DSP_A_MINWIDTH != DSP_B_MINWIDTH) match only products that already had the
wider operand on A; a product in the other order was rejected before the
normalization.

gowin: infer DSP multipliers for the GW5A family 
synth_gowin guarded the mul2dsp + dsp_map path to gw1n/gw2a, so GW5A
multiplies expanded to LUTs. Add a gw5a branch mapping the GW5A's three
multiplier widths: $__MUL27X18 (M0 27x18) for larger multiplies, $__MUL12X12
(M1 12x12) for <=12x12 (which pack two-per-block via M0+M1), and $__MUL27X36
(27x36) for wide (B>18) multiplies.

The blocks are signed-only (no per-operand sign control), so DSP_SIGNEDONLY
is mandatory without it a 32x16 -1*-1 mapping yields 0x08000001 instead of 1.
