[SHELL32] SHELL_FindExecutable: improve path handling code (#7633)

Browse Source 
Follow-up of 42d5dfd3de.
- Revert "shell32: Fix ShellExecute for non-filespec paths." https://gitlab.winehq.org/wine/wine/-/commit/0bad544aab9e2c9ee93bbabac0386e02c58a39c0.
- Apply "shell32: Look for the file name without extension also for the path search case." https://gitlab.winehq.org/wine/wine/-/commit/38b6640be91047b2cae71c103afed8a5b448542d.
- Clear leading/trailing whitespaces (an improvement by Doug Lyons).
- Update the comment for xlpFile buffer definition, to match the current code behaviour.
This fixes some failures for the following tests:
- shell32_apitest:ShellExecCmdLine: 12 failures less,
- shell32_apitest:ShellExecuteEx: 5 failures less,
- shell32_winetest:shlexec: crash fixed, now 13 failures as before,
- wshom_winetest:wshom: crash fixed, now 2 failures less too (0 failures).
I've also tested: the problem which was intended to be fixed by the guilty commit (CORE-19953) still remains fixed after this change.
CORE-19964
