pipeline: fix table state memory allocation
The regular tables, selector tables and learner tables are all sharing
the table state array. The locations in this array were computed
incorrectly, leading to memory corruption issues.

pipeline: fix annotation checks
The checks for the table-only and default-only annotations were
incorrect, as they were using the pipeline action ID instead of the
table action ID for retrieving the table action info. These checks are
now corrected and pushed into the internal table_entry_check()
function.

A previous change blamed it on compiler/ASan, while this is a real

This return -EINVAL is never reached since we test all combinations of

All branches end up with a return 0, factorize them.

pipeline: generate custom instruction functions
Generate a C function for each custom instruction, which essentially
consolidate multiple regular instructions into a single function call.
The pipeline program is split into groups of instructions, and a
custom instruction is generated for each group that has more than one
instruction. Special care is taken the instructions that can do thread
yield (RX, extern) and for those that can change the instruction
pointer (TX, near/far jump).
