hv:Replace dynamic memory allocation for vuart

Browse Source 
Replace dynamic allocation for vuart rx/tx buffer
with static array.

v2-->v3:
 --  Reduce the size of vuart tx buffer from 64K to 8K
 --  For non-partition mode, will use global rx/tx buffer,
     for partition mode, will use per VM rx/tx buffer.
 --  Change several APIs to inline
v1-->v2:
 --  Move vuart rx/tx buffer into acrn_vuart data structure
