testsuite: arm: Use -std=c17 and effective-target arm_arch_v5te_thumb

With -std=c23, the following errors are now emitted as the function
prototype and implementation does not match:

.../pr59858.c: In function 're_search_internal':
.../pr59858.c:95:17: error: too many arguments to function 'check_matching'
.../pr59858.c:75:12: note: declared here
.../pr59858.c: At top level:
.../pr59858.c:100:1: error: conflicting types for 'check_matching'; have 'int(re_match_context_t *, int *)'
.../pr59858.c:75:12: note: previous declaration of 'check_matching' with type 'int(void)'
.../pr59858.c: In function 'check_matching':

.../pr59858.c:79:12: note: declared here
.../pr59858.c: At top level:
.../pr59858.c:121:1: error: conflicting types for 'build_trtable'; have 'int(const re_dfa_t *, re_dfastate_t *)'
.../pr59858.c:79:12: note: previous declaration of 'build_trtable' with type 'int(void)'

Adding -std=c17 removes these errors.

Also, updated test case to use -mcpu=unset/-march=unset feature
introduced in r15-3606-g7d6c6a0d15c.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/pr59858.c: Use -std=c17 and effective-target
	arm_arch_v5te_thumb.
