FAT: Added support for block sizes of 512-4096 bytes

This is necessary for support of block devices with >512 byte
blocks, such as most SPI flash parts.

- Enabled support of up to 4096 byte blocks
- Added support for heap-backed buffers using _FS_HEAPBUF
  - Necessary to avoid stack overflows
  - Avoids over-aggresive allocations of _MAX_SS
- Enabled _FS_TINY to further reduce memory footprint
  - Haven't found a downside for this yet except for possible
    thread contention

FAT: Fixed volume count check when formatted without MBR

This saves 64 blocks (32KB when used with 512B blocks) and drops
the minimum storage size from 64KB to 32KB.
