Refactor classloader inspection thresholds: add memory-based size limit

Renamed INSPECTION_SIZE to INSPECTION_COUNT and repurposed INSPECTION_SIZE
to track memory usage in MB. Classloader now flushes based on either
class count+ratio or total memory size thresholds.

+Defines the threshold number of loaded classes that triggers an inspection to determine if the physical classloader should be flushed. When the total number of loaded classes (including all renamed versions) exceeds this value, Lucee checks the ratio of total classes to unique classes to determine if a flush is needed.

-Defines the threshold number of loaded classes that triggers an inspection to determine if the physical classloader should be flushed. When the total number of loaded classes (including all renamed versions) exceeds this value, Lucee checks the ratio of total classes to unique classes to determine if a flush is needed. The default value is 2000.
+Defines the memory size threshold (in megabytes) of loaded classes that triggers a classloader flush. When the total size of all loaded classes (including all renamed versions) exceeds this value, the classloader is flushed to free memory occupied by obsolete class versions. This provides an additional memory-based check alongside the count-based threshold. The default value is 100 MB.

-Defines the ratio threshold that indicates excessive memory usage from obsolete class versions. When templates are updated during development, Lucee loads new versions while old versions remain in memory, creating a "leak". This ratio (total loaded classes / unique loaded classes) measures this accumulation. A ratio of 3 means on average each unique class has 3 versions loaded. When both the inspection size and this ratio threshold are exceeded, the classloader is flushed to free memory occupied by obsolete class versions. The default value is 3.
