Use all available SDMA engines capped by xGMI bandwith for
all D2D copies within a hive.
By default, set the latency boundary copy size as 4KB and below.
Any copy size in within this boundary will not gang.
Avoid oversubscribing engines by not ganging on engines with
pending non-ganged work.
An enviroment variable HSA_ENABLE_SDMA_GANG has been provided
to override default ganging behaviour.

On gfx11, with a sequence such as
s_trap 2
s_sendmsg sendmsg(MSG_DEALLOC_VGPRS)
s_endpgm
the s_sendmsg does deallocate registers while the wave is supposed to be
stopped. As a result, the wave cannot do the expected context save
operations, and cannot context save.
To avoid this problem, park the wave in the trap handler for gfx11.
Note that gfx11 has implemented an instruction cache prefetch. When
parked, the prefetch tries to access memory past the end of trap handler
which causes memory violation exceptions to be reported. To avoid this,
we need to add padding at the end of the trap handler. The padding
consists of `s_code_end` instructions Given that the trap handler is
loaded at a 0x1000 aligned address the maximum prefetch amount (in
bytes) is given by `256 - (trap_handler_size % 64)`.

This fixes a segfault error in cases where the linking order of
compilation unit varies. Reason behind the segfault is that one
global variable in one compilation unit depends on another global
variable in another compilation unit, but there is no guarantee that
this other compilation unit is initialized first. The fix forces a
reinitialization at the first invocation of the library.

status.priv may be read after returning from the trap handler, which
causes sq_interrupt_word_wave.priv to be 0 even though the s_sendmsg
instruction was initiated when status.priv was 1.
To work around this, added a s_waitcnt lgkmcnt(0) after s_sendmsg
to make sure the message is sent before continuing.
