Currently, the sbi_timer only supports timer events configured via
SBI calls. Introduce struct sbi_timer_event and related functions
to allow configuring timer events from any part of OpenSBI.

Some of the upcoming SBI extensions (such as SSE) will directly
update register state so improve the prototype of ecall handler
to accommodate this. Further, this flexibility allows us to
push the trap redirection from sbi_ecall_handler() to the
sbi_ecall_legacy_handler().

Rather than registering all extensions on their behalf in
sbi_ecall_init(), introduce another extension callback and
invoke that instead. For now, implement each callback by
simply registering the extension, which means this patch
has no intended functional change. In later patches, extension
callbacks will be modified to choose when to register and to
possibly narrow the extension ID range prior to registering.
When an extension range needs to remove IDs, leaving gaps, then
multiple invocations of sbi_ecall_register_extension() may be
used. In summary, later patches for current extensions and the
introductions of future extensions will use the new callback to
ensure that only valid extension IDs from the initial range,
which are also available, will be registered.

Split up sbi_ecall_replace so that each extension is in its individual
file.
Also reorganize the corresponding section in lib/sbi/objects.mk so
that it is grouped by extension, now that the object file targets are
split up.
