Mapping expressions that have `this` as their base expression aren't
considered a valid base variable and the rest of the runtime expects
this. However, if we have an expression with no value declaration we can
try to extract it manually to provide more helpful debuggin information.

This patch fixes a bug from D89802. For example, without it, Clang
generates x as the debug map name for both x and y in the following
example:
```
#pragma omp target map(to: x, y)
x = y = 1;
```

Summary:
Currently the mapping names are not passed to the mapper components that set up
the array region. This means array mappings will not have their names availible
in the runtime. This patch fixes this by passing the argument name to the region
correctly. This means that the mapped variable's name will be the declared
mapper that placed it on the device.

Summary:
The custom mapper API did not previously support the mapping names added previously. This means they were not present if a user requested debugging information while using the mapper functions. This adds basic support for passing the mapped names to the runtime library.

Summary:
Add support for passing source locations to libomptarget runtime functions using the ident_t struct present in the rest of the libomp API. This will allow the runtime system to give much more insightful error messages and debugging values.

Summary:
This patch adds support for passing in the original delcaration name in the source file to the libomptarget runtime. This will allow the runtime to provide more intelligent debugging messages. This patch takes the original expression parsed from the OpenMP map / update clause and provides a textual representation if it was explicitly mapped, otherwise it takes the name of the variable declaration as a fallback. The information in passed to the runtime in a global array of strings that matches the existing ident_t source location strings using ";name;filename;column;row;;"
