Series apple: dart: Add driver specific instance of LMB | expand

Commit Message

Sughosh Ganu Oct. 29, 2024, 7:18 a.m. UTC 
The LMB module uses a separate instance of the lmb structure when
running tests. Setting up the correct instance is done using the
lmb_push() and lmb_pop() functions. In addition to pushing and popping
the lmb instances, these functions are also doing some test specific
operations. Move these operations to lmb_test_push() and
lmb_test_pop() functions, so that lmb_push() and lmb_pop() can be
called from elsewhere.
