c1779f33 - [flang] Implement !DIR$ [NO]INLINE and FORCEINLINE directives (#134350)

[flang] Implement !DIR$ [NO]INLINE and FORCEINLINE directives (#134350) This patch adds the support of these two directives : `!dir$ inline` and `!dir$ noinline`. - `!dir$ noinline` tells to the compiler to not perform inlining on specific function calls by adding the `noinline` metadata on the call. - `!dir$ inline` tells to the compiler to attempt inlining on specific function calls by adding the `inlinehint` metadata on the call. - `!dir$ forceinline` tells to the compiler to always perfom inlining on specific function calls by adding the `alwaysinline` metadata on the call. Currently, these directives can be placed before a `DO LOOP`, call functions or assignments. Maybe other statements can be added in the future if needed. For the `inline` directive the correct name might be `forceinline` but I'm not sure ?
