  [ELF] Fix location counter used for output section address with MEMOR… (#197293)

When a section uses '.' as its address expression inside a MEMORY region
(e.g. 's02 . : { ... } > FLASH'), lld was incorrectly evaluating '.'
against the memory region's current position instead of the global
location counter. Save the global dot before the memRegion override and
restore it when an explicit addrExpr is present.

Fixes #112919
