MDEV-19522 InnoDB commit fails when FTS_DOC_ID value is greater than 4294967295

InnoDB commit fails when consecutive FTS_DOC_ID value
is greater than 4294967295.
Fix is that InnoDB should remove the delta FTS_DOC_ID
value limitations and fts should encode 8 byte value,
remove FTS_DOC_ID_MAX_STEP variable. Replaced the
fts0vlc.ic file with fts0vlc.h

fts_encode_int(): Should be able to encode 10 bytes value

fts_get_encoded_len(): Should get the length of the value
which has 10 bytes

fts_decode_vlc(): Add debug assertion to verify the maximum
length allowed is 10.

mach_read_uint64_little_endian(): Reads 64 bit stored in
little endian format

Added a unit test case which check for minimum and maximum
value to do the fts encoding
