v3d/compiler: fix QPU scheduler TMU sequence shuffling

The QPU scheduler allows to move certain TMU instructions around and
since we enabled pipelining, we need to protect against the case where
doing this might break a TMU sequence. For example, this test:

dEQP-VK.rasterization.line_continuity.line-strip

Was generating this VIR:

mov tmud, t187
mov.pushz null, t176
mov.ifa tmua, t9
nop null; wrtmuc (img[0].p0 | 0x0)
mov tmut, t185
mov tmud, t180
mov.ifa tmusf, t183
nop null; thrsw

where we have a general TMU access (tmud,tmua) followed by an image
access (wrtmuc, tmut, tmud, tmusf), which the QPU scheduler was turning
into:

nop            ; nop               ; ldunifrf.rf22 (0xffffff00 / -nan)
nop            ; nop               ; wrtmuc (img[0].p0 | 0x0)
nop            ; nop               ; ldtmu.r2
add  r0, r2, 1 ; nop               ; ldtmu.r3
nop            ; nop               ; ldtmu.r4
nop            ; mov  tmud, r0
nop            ; mov.ifa  tmua, rf15
nop            ; mov  tmut, r4     ; thrsw
nop            ; mov  tmud, rf22
nop            ; mov.ifa  tmusf, r3

where it allowed the wrtmuc to move up and before the general TMU access,
leading to an incorrect TMU sequence.

Fix this by flagging TMUA writes (which are the sequence terminators for
general TMU accessess) as writing new TMU configuration, like we do for all
other TMU sequence terminators for textures and images.
