remote_bitbang: make send_buf class member

Currently send buffer is static variable in function, which makes it's
impossible to have multiple concurrent instances of remote bitbang
class, since all of them would share this static buffer.
Thus, make send_buf a class member.

stimecmp: perform menvcfg.STCE permission check when accessing vstimecmp in HS-mode

The spec requires menvcfg.STCE=1 on accessing stimecmp or vstimecmp in a
mode other than M-mode. The previous implementation does not check the
permission on accessing vstimecmp in HS-mode. This commit fixes the
issue by moveing the permission check from virtualized_stimecmp_csr_t to
stimecmp_csr_t, which implements the vstimecmp.

Resolves #1507

Update debug smoketest action.

fesvr/htif: allow exit on SIGINT.

Currently signal handler would call exit() only on second received
signal, this prevent proper program cleanup.
Instead use signal flag to exit loop.
