[PDB] Add PDBSourcePath flag to support absolutize source file path 

This patch changes relative path for source files in obj files to
absolute path in PDB when linking with added flag.

I will make obj file generated by clang-cl independent from build
directory for chromium build. But I don't want to confuse visual studio
debugger or require additional configuration. To attain this goal, I
added flag to convert relative source file path in obj to absolute path
when emitting PDB.

By removing absolute path from obj files, we can share build cache
between chromium developers even when they are doing debug build.
That will make build time faster.

Test the linker line tables on roughly the following example:
==> foo.h <==
void bar(void);
inline void foo(void) {
bar();
}
==> pdb_lines_1.c <==
#include "foo.h"
int main(void) {
foo();
return 42;
}
==> pdb_lines_2.c <==
void bar(void) {
}
