Fix incorrect source file name for inlined frames

Browse source 
Processor shows incorrect source file name if a frame have an inlined
frame and their source files are different.
Consider this example:
FILE 0 /tmp/a.h
FILE 1 /tmp/a.cpp
INLINE_ORIGIN 0 0 foo()
FUNC 1110 a 0 main
INLINE 0 22 0 1110 7
1110 7 3 0
1117 3 23 1

When querying the address 0x1110, we know this line 0x1110 corresponds
to /tmp/a.h line 3 and it's inside a inlined function foo() which is
defined at /tmp/a.h and called at line 22. But we don't know at which
file it's being called at line 22. So, we will get stacks like this:
void foo() /tmp/a.h:3
int main() /tmp/a.h:22

The correct stacks should be this:
void foo() /tmp/a.h:3
int main() /tmp/a.cpp:22

In this change:
1. Remove file_id field for INLINE_ORIGIN record.
2. Add call_site_file_id for INLINE record to represents the file where
this call being inlined.

After adding call_site_file_id to it (as third field), it looks like
this:
FILE 0 /tmp/a.h
FILE 1 /tmp/a.cpp
INLINE_ORIGIN 0 foo()
FUNC 1110 a 0 main
INLINE 0 22 1 0 1110 7
1110 7 3 0
1117 3 23 1
