cmd/asm: add mode to collect symbol ABIs
This adds a -symabis flag that runs the assembler in a special mode
that outputs symbol definition and reference ABIs rather than
assembling the code. This uses a fast and somewhat lax parser because
the go_asm.h definitions may not be available.
For #27539.
