* Bump borsh to 0.10.3
transaction-status relies on SPL which still requires borsh 0.9, so
until SPL also gets updated that package alone will use an older version of
borsh.
* ci: Temporarily disable spl and openbook-dex builds
* Add docs for system_instruction and some of its functions
* Apply suggestions from code review

* Apply review feedback
* Use PDAs in system_instruction examples
* Fix 'bump seed' terminology in system_instruction docs

permanently disables durable transactions with legacy nonce versions
which are within chain blockhash domain.
This commit adds a new system instruction for a one-time idempotent
upgrade of legacy nonce accounts in order to bump them out of chain
blockhash domain.
AdvanceNonceAccount instruction updates nonce to blockhash. This makes it
possible that a durable transaction is executed twice both as a normal
transaction and a nonce transaction if it uses blockhash (as opposed to nonce)
for its recent_blockhash field.
The commit prevents this double execution by separating nonce and blockhash
domains; when advancing nonce account, blockhash is hashed with a fixed string.
As a result a blockhash cannot be a valid nonce value; and if transaction was
once executed as a normal transaction it cannot be re-executed as a durable
transaction again and vice-versa.
