rawmidi: rename enum snd_rawmidi_framing to snd_rawmidi_read_mode
...
We hide the internal data transfers using the data frames. Rename
the snd_rawmidi_framing enum to snd_rawmidi_read_mode to make
API more straight and understandable.

rawmidi: define more abstract API for the timestamp reads
...
The frame structure is a bit internal thing for the kernel
data transfer implementation. Introduce snd_rawmidi_tread()
function which is straight for the application usage and hides
the framing data transfers (kernel space API).
The current code implements the read cache and does the merging
of the frame reads with the similar timestamps (opposite
to the kernel data split for big chunks).
If the application wants to use super-duper-lighting-fast reads,
the snd_rawmidi_read() may be used, but the structure must be
defined on it's own, because this mechanism is not preferred
and unsupported.

rawmidi: Use the standard types for snd_rawmidi_framing_tstamp_t definition
...
Using the kernel-specific types like __u8 breaks the compilation of
applications. Also we need the packed attribute.
Although we may want to move to an opaque type later, let's put the
workaround at first.

rawmidi: Add rawmidi framing API
...
Optionally, incoming rawmidi bytes can be put inside a frame of type
snd_rawmidi_framing_tstamp_t.
The main current benefit is that can enable in-kernel timestamping of
incoming bytes, and that timestamp is likely to be more precise than
what userspace can offer.
Tstamp type framing requires a kernel >= 5.14 and a buffer size that
is a multiple of sizeof(snd_rawmidi_framing_tstamp_t). It is only
available on input streams.

Remove assert from header files
...
Putting assert in the public macros isn't good idea at all.
Let's get rid of them.
Also, clean up snd*_alloca() functions to use a helper macro
instead of copy and paste.
