Gwendal Grignou 92ea78398b common: Add deferred erase support ...

Some device has large pages that take up to 2s to erase.
Add support to send a deferred erase command, that willi
be processed on HOOK task.

It can leave the other tasks (HOST_CMD) responsive.
If the whole EC can stall on flash erase, like the STM32F4 do,
at least the command FLASH_ERASE_GET_RESULT can be retried when it times
out.

BRANCH=none
TEST=Check with flashrom doing a loop of overwrites.
BUG=b:38018926
